Which two countries are nuclear capable allies of the USA?

France and the United Kingdom are classified as nuclear-capable allies of the United States due to their established nuclear arsenals and strategic military cooperation. Both countries possess significant nuclear stockpiles and have been recognized as nuclear powers since the latter half of the 20th century.

The nuclear partnership with the United States includes sharing intelligence, military strategies, and technologies related to nuclear capabilities, which enhances collective security and defense preparedness among these nations. This trilateral relationship is prominently evidenced in various defense collaborations, including joint exercises and deterrence strategies.

While other nations may have close alliances with the USA and play important roles in NATO and global security, they do not possess nuclear weapons or operate nuclear-capable forces like France and the United Kingdom. For example, Germany and Japan are strong allies but do not have nuclear arsenals of their own due to their post-World War II policies aimed at non-proliferation. Similarly, Italy and Spain as well as Canada and Australia maintain close defense ties with the U.S. but do not have nuclear weapons capabilities.
