The success of the global nuclear nonproliferation and disarmament system has always relied on effective cooperation and dialogue between the two largest nuclear-weapon states.

The strike did not compromise safety at the nuclear power plant but represents a dangerous new stage in Russia’s war on Ukraine. 

The U.S. said it will find an alternate way to report on North Korean sanctions enforcement. 

The veto fueled concerns that Moscow is developing a space-based nuclear anti-satellite capability. 

During an era when nuclear weapons threats are growing, Assistant Secretary of State Mallory Stewart is among the top U.S. officials working to increase stability, prevent conflict, and preserve and advance effective arms control and disarmament measures.

The intelligence community remains concerned that Russia could resort to the use of nuclear weapons in Ukraine and that North Korea is maneuvering to win acceptance as a nuclear- weapons state.

The accusations of North Korean involvement came from the United States, which promised to respond by imposing additional sanctions.

The head of the International Atomic Energy Agency said Russia’s decision to cut staff at the Zaporizhzhia Nuclear Power Plant compromises safety. 

The decision means that the remaining Russia-U.S. nuclear arms control treaty limiting the world’s largest nuclear arsenals will expire in 2026.

Using riot control agents in Ukraine is prohibited by the Chemical Weapons Convention, Ukraine said.

The anti-satellite weapons system would violate the Outer Space Treaty.

Fifty-seven years ago, through the Outer Space Treaty, the United States and the Soviet Union agreed to codify a fundamental nuclear taboo: nuclear weapons shall not be stationed in orbit or elsewhere in outer space.
