The United States’ strategic posture is currently marked by significant uncertainty and contradictory signals.
On the one hand, President Donald Trump has repeatedly expressed his intention to reduce the role of nuclear weapons, even suggesting steps toward denuclearization and renewed arms control discussions with Russia and China. On the other hand, his administration has continued—and in some cases accelerated—programs to modernize the U.S. nuclear arsenal and introduced the controversial project of the Golden Dome missile defense system in order to maintain a strategic advantage over Moscow and Beijing. This ambiguity, now at the heart of his second term, raises numerous questions about the evolution of U.S. nuclear doctrine and its implications for international stability.

This "nuclear sharing" arrangement, central to the Alliance since its founding, has long been contested by public opinion, political parties, and civil society across Europe, without ever being abandoned by host governments. This paradox lies at the heart of the seminar: why does such an unpopular policy persist?
