[1/3] Russian President Vladimir Putin delivers his annual address to the Federal Assembly in Moscow, Russia February 21, 2023. Since invading Ukraine a year ago, he has repeatedly boasted about Russia's nuclear arsenal and said he would be willing to use it if the country's "territorial integrity" is threatened. TREATY LIMITSThe 2010 New START treaty limits each country's deployed nuclear warheads to 1,550 - which Russia has also said it will continue to observe - and deployed missiles and heavy bombers to 700. Asked in what circumstances Russia would return to the deal, Kremlin spokesman Dmitry Peskov said: "Everything will depend on the position of the West... Russia is now demanding that British and French nuclear weapons targeted against Russia should be included in the arms control framework, seen as a non-starter for Washington after more than half a century of bilateral nuclear treaties with Moscow.
