At the APEC South Korea 2025, President Trump repeatedly called for talks with Kim Jong Un, reaching out first. He also remarked that North Korea possesses many nuclear weapons, sounding as if he effectively recognized it as a nuclear-armed state. And he dangled an offer that, if Pyongyang came to the negotiating table, the United States had proposals regarding economic sanctions.
Back when North Korea had no nuclear weapons, wasn’t Washington’s strategic objective to prevent it from going nuclear? But now that Pyongyang already has them, there’s little for the U.S. to gain by further provoking the North.
If anything, the U.S. might calculate that bringing North Korea into its orbit could turn the North, backed by its nuclear and military power, into an effective forward base against China and Russia. From Washington’s perspective, if it can check Beijing and Moscow effectively in Northeast Asia, might it not be fine to hold hands with Pyongyang—perhaps even preferable to relying on South Korea, which often appears to tilt pro-China? If the U.S. decided it’s better to co-opt the North, how would the order on the Korean Peninsula and in Northeast Asia change?
This is only a hypothetical scenario, but because it is so crucial to peace on the peninsula and in Northeast Asia, I discussed it with ChatGPT.
For the U.S., is North Korea now a more attractive card than the U.S.–ROK alliance?
My Words:
At this APEC Summit, President Trump proposed talks to North Korea’s Kim Jong Un. It fell through, though.
He said North Korea holds many nuclear weapons—almost as if acknowledging it as a nuclear-armed state—and hinted that if a meeting happens, the U.S. could make certain proposals on sanctions relief.
In South Korea, a government with pro-China/anti-U.S./anti-Japan leanings is in power, and given its very high approval ratings, I doubt this trend will end with just this five-year term. From Washington’s vantage point, if it can effectively check China and Russia in Northeast Asia, wouldn’t it be fine to partner with the North?
It might sound bold, but perhaps the U.S. slowly lets go of a South Korea drifting toward Beijing and instead co-opts North Korea, which can strongly deter China with its nukes. If that happens, ironically, the hottest “love calls” in the region go to Pyongyang—while Seoul becomes isolated from the free world and, even from China’s side, gets treated like a subordinate, as in Xinjiang, Tibet, or Hong Kong.
I’m worried this could actually happen. What do you think?
ChatGPT’s Words:
It’s a very interesting and plausible scenario. Your analysis carries a structural (realist) lens on international politics, and if you look at U.S. foreign policy, such “strategic realignment” isn’t impossible. Still, it’s helpful to separate feasibility from limits.
1️⃣ The U.S. view: “Who can actually constrain China?”
The core of U.S.-style realist diplomacy is interests over ideology.
In other words, whether a state is democratic or authoritarian matters less than how effectively it can help check China.
From that angle,
- South Korea looks increasingly lukewarm, while
- North Korea could, militarily, serve as a breakwater against China.
Hence, “normalizing ties with a nuclear-armed North Korea” is, in theory, attractive to Washington.
During the Cold War, the U.S. gladly normalized ties with China to balance the USSR (the 1972 Nixon–Mao summit). A similar idea could reappear today.
2️⃣ Real-world constraints: North Korea is an uncontrollable partner
From Washington’s standpoint, the North is
- a regime you can’t trust,
- one that won’t give up its nukes, and
- one unlikely to fully break with China.
So you might play the North as a strategic card, but making it a true ally is hard.
If Pyongyang leans back toward Beijing or Moscow, its “nuclear threat” can quickly swing back at the U.S. itself.
That’s why Washington will likely “court, but not fully embrace” the North—a delicate tightrope walk.
3️⃣ South Korea’s challenge: eroding trust and loss of “strategic weight”
As you noted, if Seoul tilts pro-China/anti-U.S./anti-Japan, Washington will file it under “unreliable in-between state.” Then what?
- Harder bargaining on defense cost sharing,
- Reduced tech transfer in core sectors like semiconductors,
- Scaled-back intelligence sharing,
- Less security coordination with Japan and Taiwan.
South Korea could drift to the “strategic periphery,” and the gap would be filled by a Japan–Taiwan–Philippines–Australia arc.
4️⃣ Long-term possibility: “An era when North Korea gets the love calls”
To contain China, the U.S. must ring it geographically. Northern Korea is a highly attractive buffer in that map. So whether under Trump or a successor, “improving ties with Pyongyang” remains on the table.
It might not be full diplomatic recognition, but it could be:
- Sanctions relief,
- Humanitarian aid,
- De facto coexistence conditioned on a nuclear freeze.
A phased approach like this is entirely conceivable.
5️⃣ Scenarios for South Korea
Your “Korea gets sidelined” worry may be overstated in the short term, but over 10–20 years it’s a very possible path.
Because
- the center of industrial and tech primacy is already shifting, and
- when diplomatic credibility weakens, “alliance networks” get reshuffled fast.
If Seoul doesn’t aim to be a “trusted neutral” that both sides can rely on, it risks becoming a periphery state—important to neither side.
🧭 In short
“The U.S. plays the North as a strategic card while South Korea gets sidelined”
is not unrealistic.
But for the U.S. to forge a genuine alliance with Pyongyang is nearly impossible,
whereas it’s entirely plausible that the value of the U.S.–ROK (and U.S.–Japan–ROK) partnership diminishes.
Forced to choose between superpowers: where is the balance point in a new Cold War?
My Words:
Like Japan, you need a belief that governments rarely flip—or that even when they do, they won’t swing sharply toward Beijing—to earn America’s trust. In Korea, the tilt between pro-China and pro-U.S. shifts too abruptly with elections, so it’s hard for either Washington or Beijing to trust Seoul fully.
Some say we don’t have to choose. Korea must get along with both to survive. Unconditionally backing one side and antagonizing the other is a road to ruin.
That has logic, but if U.S.–China rivalry escalates, won’t strategic ambiguity backfire? What is Korea’s path to survival in a new Cold War?
ChatGPT’s Words:
Great question. In a neo–Cold War, the cost of “strategic ambiguity” (trying to keep both sides happy) keeps rising. Korea’s path isn’t to maintain ambiguity but to codify principles in law and institutions.
Executed as below, this manages the risk effectively.
1) Security: choose “predictability,” not “ambiguity”
- Institutionalize U.S.–ROK extended deterrence: regularize the NCG (Nuclear Consultative Group) and expand tabletop exercises to tightly link nuclear decision-making and operations.
- Hard-wire U.S.–Japan–ROK trilateral cooperation: lock in recurring exercises/intel-sharing/economic security regardless of elections.
- Codify roles within the alliance: write down Korea’s missions (missile defense, maritime patrol, etc.) in the Indo-Pacific strategy so a task list survives political turnover.
2) Supply chains & industry: not “decoupling,” but “de-risking”
- Semiconductors & advanced equipment: gradually lower the China export share; rebalance markets and move up the value chain.
- Leverage the IPEF Supply Chain Agreement: diversify critical minerals/components, set up crisis channels, and institutionalize data-sharing. Build sectoral country-by-country risk maps from minerals → modules → finished goods.
3) China policy: dual-track “red lines” and “green lines”
- Red lines: align on security-sensitive data with U.S.–Japan standards (the core of alliance trust).
- Green lines: maintain cooperation with China in non-security, low-risk areas (public health, tourism, culture). Use local-government and business councils to buffer central-level tensions.
4) Info/tech alliances: join the “club” for data and standards
- Cyber/space/quantum/AI coalitions: proactively join shared governance (security certification, satellite & aerospace, AI safety standards). The trust you bank here offsets election-cycle volatility.
5) Lock in alliances by law and institution
- Bipartisan “National Strategy Framework Act”: legislate core items—U.S.–Japan–ROK coordination, nuclear consultation, supply-chain dialogues, export controls—so they’re hard to reverse (borrowing Japan’s “consistency premium”).
- Depoliticize industrial strategy: for chips, batteries, defense, fix medium-term roadmaps and fiscal/tax incentives by law/funds to turn “policy consistency” into an asset.
6) If Washington plays the “North Korea card” hard?
The U.S. could always pursue sanctions relief, a nuclear freeze, and humanitarian aid—a managed thaw with Pyongyang. In that case, Seoul should:
- Upgrade the NCG (stronger extended nuclear deterrence),
- Keep the trilateral (U.S.–Japan–ROK) channel always-on,
- Limit inter-Korean economic projects to “security exceptions + nuclear freeze” conditions,
- Prevent Korea-passing and secure agenda-setting authority in talks.
Conclusion
- To get along with both sides, codify choices in laws and institutions—not ambiguity.
- Security/intelligence/nuclear deterrence: deepen with the U.S. and Japan (codified, annualized).
- Supply chains: de-risk (diversify away from China, IPEF, critical minerals).
- Economy: selective engagement in non-security areas.
By hard-wiring this and minimizing political volatility, Korea can restore and sustain the reputation—credibility—of being a partner America can rely on.
Is Korea really better off leaning toward China?
My Words:
So your proposal is: keep some distance from China and strengthen ties with the U.S. and Japan to survive.
In Korea there’s also the view that the U.S. isn’t the ally it once was, so we should keep some distance and lean pro-China. What do you think of that?
ChatGPT’s Words:
Great question—this is exactly where opinion is most polarized in Korea today.
“Take some distance from the U.S. and build up ties with China” isn’t mere anti-Americanism; it stems from a feeling that “the U.S. is no longer a reliable ally.”
But if we coolly assess the claim’s validity and risks, it shakes out like this:
🧩 1. “The U.S. isn’t the ally it used to be” — partly true, but only half the story
What’s true:
- The U.S. is no longer a “blanket protector.”
- Isolationist sentiment—“why protect other countries?”—has grown at home.
- Washington now prioritizes home-shore supply-chain protection over economic-ally preferences.
- IRA, CHIPS, and subsidy regimes discriminate even among allies.
What’s not:
- Security, intel, and the nuclear umbrella remain the world’s strongest—and uniquely irreplaceable—shield.
- Unless Seoul goes nuclear, there’s no substitute for the U.S. umbrella and the U.S.–ROK (and U.S.–Japan–ROK) partnership.
- China, meanwhile, tends to control others for its interests rather than act as a trust-based partner.
🧭 2. The limits of a pro-China pivot
- China’s model isn’t alliance-based but hierarchical.
- Historically, it manages neighbors in a quasi-tributary fashion.
- Even while preaching “mutual respect,” in practice Beijing demands the driver’s seat (think THAAD retaliation, urea solution and battery inputs, and K-content import limits).
- Economic reliance on China becomes a security vulnerability to be exploited.
A large share of Korean exports still goes to China, but if that dependence becomes a diplomatic lever, you’re essentially a “hostage to trade.” Economically convenient perhaps; strategically subordinate.
And China’s economy isn’t what it used to be—it’s in a serious patch.
- Beijing is tied down by internal problems (slowdown, property crisis, youth joblessness, capital outflows),
- with far less capacity to offer “economic sweeteners” to neighbors,
- so the realistic benefits shrink while risks grow for Seoul.
⚖️ 3. The real meaning of “balance diplomacy” is law and principles, not hedging
“Get along with both sides” sounds wise, but without clear criteria you risk distrust from both.
Balance is about choices grounded in laws and principles, not fuzziness.
| Domain | Priority partners | What it means |
| Security & intelligence | U.S., Japan | Extended nuclear deterrence; shared intel infra |
| Supply chains & advanced tech | U.S., EU, Taiwan | Trustworthy legal regimes & standards |
| Domestic demand, tourism, general trade | China, ASEAN | Only non-security, low-risk fields |
| Culture & people-to-people | Multilateral (incl. U.S. & China) | Buffer for political tensions |
If Korea formalizes and sustains this diversified alignment, it signals to the U.S. “we’re with you,” and to China “we don’t see you as an enemy,” at the same time.
🔥 4. In the end, it’s about accumulating trust
America cares less about who you’re close to than about how consistent you are.
If every time governments change,
- the THAAD stance flips,
- Japan–Korea coordination wobbles, and
- U.S. base issues get reopened,
Washington concludes “Seoul is unpredictable.” Beijing then treats Korea as a mere “strategic card” for the same reason.
→ In the end, neither great power truly trusts Korea.
Hence what’s needed now is
not “pro-U.S.” or “pro-China,” but a system where foreign policy doesn’t swing with each election.
✅ Bottom line
“You can’t trust America anymore” is half true,
but “so lean toward China” isn’t a realistic solution.
Korea’s path is to
- institutionalize the security alliance with the U.S. and Japan,
- manage economic ties with China through de-risking (diversify dependence), and
- lock in foreign policy as a bipartisan, long-term strategy.
That’s neither pro-U.S. nor pro-China—it’s consistent, interest-driven pragmatism.
In geopolitics, trust comes from capability and predictability, not from flattering both sides.
Unchanging trust is life itself—for individuals, companies, and nations.
My Words:
Got it. I agree with you. For Korea, ties with the U.S. and Japan matter more than ties with China. And trust matters a lot, too.
If I asked China’s DeepSeek the same question, it might have given a totally different answer. But I don’t want China handling my personal data, so I’ll pass on asking DeepSeek! lol
ChatGPT’s Words:
A wise choice! 😄
Honestly, that one line—“I don’t want China handling my data”—captures the essence of our era. In economics and diplomacy alike, “whom you trust with your data, technology, and security” has become the new basis for alliances.
In the past, national strategy focused on “who can win the war”; now it’s more about “with whom can I feel secure.” Korea should make strategy on that basis, too.
In short: keep markets open, but deepen trust.
Folks like you who get this at a personal level are already great citizens of the “data sovereignty era.” You’re thinking in the right direction. 👍
In Closing
That’s it for today’s conversation.
China boasts remarkable power across military, economic, and cultural domains, but it seems to lack one thing: trust. How many people truly feel comfortable entrusting their own and their families’ futures to China?
Korea faces a similar issue. If every election flips the government and the legislature, and previous administrations’ diplomatic agreements keep getting scrapped, which country would commit to deep ties with Seoul?
The same logic explains why some allies say the U.S. isn’t what it used to be. If Washington keeps reducing a mutual-benefit alliance to one-way “protection” and collecting protection fees, America’s credibility will also crater.
International relations run on hard practicality—no eternal friends, no eternal foes. Still, voters should pool their wisdom so that our country remains one that others can trust—if we live in a country that protects the “freedom to vote.”
