"The United States provides about 180 tactical B61 nuclear bombs for use by Belgium, Germany, Italy, the Netherlands and Turkey under a NATO nuclear weapons sharing agreement. Some countries believe this violates Articles I and II of the Nuclear Non-Proliferation Treaty, where the U.S. has committed:
"... not to transfer to any recipient whatsoever nuclear weapons or other nuclear explosive devices or control over such weapons or explosive devices directly, or indirectly...".
The U.S. insists its forces control the weapons and that no transfer of the nuclear bombs or control over them is intended "unless and until a decision were made to go to war, at which the [NPT] treaty would no longer be controlling", so there is no breach of the NPT. However the pilots and other staff of the "non-nuclear" NATO countries practice handling and delivering the U.S. nuclear bombs."
does anyone know more about this?
