Artificial intelligence is becoming a new arms race, and to avoid repeating the mistakes of the past perhaps a drastic unification of competing models could prevent catastrophe.

The risks of unintended maritime and aerial incidents triggered by more frequent and complex military activity are no longer confined to the China-U.S. relationship. They are extending into a more complicated and less predictable multilateral environment.

The focus of the Russia-Ukraine war is shifting from front-line engagements to deep-strike operations, while the central arena of competition is increasingly defined by each side’s capacity to sustain the war effort. In this evolving landscape, drones have emerged as a pivotal force.

The summit illustrated that NATO is evolving from a traditional alliance founded on shared values and underwritten by American security guarantees into an alliance increasingly defined by capabilities, responsibilities and transactions.

Great powers have long made policy toward an imagined Iran—one that none of them had the patience to truly understand. Now, the great powers must rely on deep understanding, mutual respect and presence. But presence is precisely what Washington and Beijing lack.

The U.S.-Iran memorandum of understanding is only a political commitment and carries no legally binding force. What truly matters is whether the two sides can conclude a formal peace agreement within the 60-day negotiating period. Three formidable hurdles stand in the way.

The policy is turning the world from a rules-based order to a strength-based one. January’s intervention in Venezuela may have seemed like a great success for the Trump Corollary, but it was actually a self-defeating gamble—physically controlling Venezuela in a short time but damaging U.S. soft power, its alliance system and its global strategic interests in the long run.

China-U.S. relations face both opportunities and challenges. At least within this year, and particularly given the three forthcoming meetings between the two heads of state, the opportunities outweigh the challenges as relations continue to move forward.

Great powers can explore paths toward peaceful coexistence. The most important lesson of the Reykjavik Summit in 1986 was not that competition can be eliminated but that it requires clear boundaries. The real challenge is not the removal of differences but preventing their escalation into conflict.

At the recent Shangri-La Dialogue in Singapore, US Defense Secretary Pete Hegseth pressed America’s Asian allies to spend 3.5% of their GDP on defense, fueling anxiety across the region and beyond. His brow-beating call to arms may well bring about a regional defense build-up on a scale unseen since the Cold War’s end.
