Actions by U. S. President Donald Trump risk pushing the world toward a more dangerous phase of nuclear confrontation, according to a Bloomberg report. The concern is not only about Washington’s willingness to use force against its adversaries, but also its readiness to exert pressure on allies.

Analysts note that the hardline approach adopted by the United States — including its standoff with Iran — could trigger a wider chain reaction. More governments are beginning to weigh the prospect of developing their own nuclear arsenals, and such discussions are already gaining traction at the policy level.

Countries that once relied on the American «nuclear umbrella» are increasingly reconsidering that dependence. Some are now gravitating toward the idea put forward by French President Emmanuel Macron, who has suggested extending France’s nuclear deterrence to other European nations.

At the same time, the head of the International Atomic Energy Agency, Rafael Grossi, has warned that a growing number of nuclear-armed states would make the world less secure, not more. He has emphasized the importance of upholding non-proliferation principles.

That view, however, is far from universal. A number of countries argue that abandoning the pursuit of nuclear capabilities could leave them exposed. Bloomberg reports that more than 20 states already possess the technological and industrial capacity that could, in theory, enable them to develop nuclear weapons. Discussions around such programs are becoming increasingly open.

Experts caution that if this trend continues, the existing system of arms control could come under serious strain. One analyst from the Pacific Forum described a potential domino effect in which instability in one region could spill into another, raising risks across both the Middle East and East Asia and making those regions significantly more volatile.

Earlier reports also indicated that Iran is considering withdrawing from the Treaty on the Non-Proliferation of Nuclear Weapons following U.S. and Israeli strikes on its nuclear infrastructure.
