Direct NATO-Russia clash would trigger "World War 3", warns Biden

US President Joe Biden has warned  that Russia would pay a “severe price” if it used chemical weapons in Ukraine, while also pledging to avoid provoking Moscow into “World War III” "I'm not going to speak about the intelligence, but Russia would pay a severe price if they used chemicals," Biden on Fridaysaid as he announced a raft of new sanctions against Moscow.  Biden reacted after Russia accused Ukraine and the United States of developing biological and chemical weapons -- in what Western nations says is a ruse to lay the ground for Moscow's own possible use of them in the conflict.

Biden again underlined that US forces would not fight in Ukraine, despite the desperate pleas of many Ukrainians. Biden also moved to end normal trade relations with Russia, further racheting up pressure on President Vladimir Putin after the bloody invasion of Ukraine.The United States, like other Western nations, is sending millions of dollars of weapons such anti-aircraft and anti-tank missiles to Ukraine, as well as sharing intelligence. In 2018, Moscow accused the United States of secretly conducting biological weapons experiments in a laboratory in Georgia, another former Soviet republic that, like Ukraine, has ambitions to join NATO and the European Union.
