Russia demands end to US hostility for return to nuclear arms treaty.

Russian Deputy Foreign Minister Sergei Ryabkov has stated that Moscow's decision to suspend its nuclear arms treaty with Washington was "unshakable" and could only be reversed if the US abandons its "hostile" policy towards Russia. The US Department of State announced a set of four countermeasures in response to Russia's violations of the New START Treaty. The New START treaty limited the number of US and Russian nuclear warheads and intercontinental ballistic missiles. The treaty was signed in 2010 and is due to expire in 2026.
