“US says Russia planned fake video as ‘false flag’ to invade Ukraine” Translation: “The US is planning to stage a ‘false flag’ in order to start a war.
Likely true, can't believe anybody at this stage.
That doesn’t explain this claim at all. If the US wanted to “start” a war it would be US troops massing on the border of Russia, not Russian troops massing on the border with Ukraine. Note that Russia previously used claims of Ukrainian aggression to justify taking over lands to “protect” ethnic Russians living there, and that was before grabbing Crimea.
Putin has already made it clear he wants all of Ukraine, and then some.
You don’t “start” a war by predicting your opponent will carry out a “false flag”... Predicting your opponent will do so is at most, an attempt by a weak administration that is in no way prepared to fight a war, to avoid the risks of directly punching the Russians in the nose, such as what Trump did to take out a number of Russian mercs. Biden doesn’t want Putin to embarrass him. He just wants Putin to wait and take Ukraine on someone else’s watch.
