NATO fighting a war against Russia in Ukraine would be World War III, Joe Biden has warned.
The US President said American troops will not be sent to Ukraine. But he added: "I want to be clear: We will defend every inch of Nato territory with the full might of a united and galvanised Nato."
In a video address released in the early hours of this morning, President Biden said: "We will make sure Ukraine has weapons to defend against an invading Russian Force... We will send money and food and aid to save the Ukrainian people - and I will welcome Ukrainian refugees. We should welcome them here with open arms.
