Russia Ukraine war, page-19789

Your first two sentences are total BS.

"So far the US has not sent any troops to fight in Ukraine against the attacking Russians, let alone declared war on Russia."

Actually the US and Canada have sent official and unofficial military trainers to Ukraine so again you are full of it.
The US/NATO war against Russia is happening right now, it is just undeclared and using Ukrainian bodies not US/NATO bodies yet.
You are pretending you don't know what a proxy war is.

President Biden's deliberate lies are being used to justify direct war against Russia which certainly does raise the threat of a nuclear exchange and has been planned and prepared for, over many years.
It's certainly not the fault of the WSWS if you have such a blinkered view that you can't see or admit what is happening directly in front of us.
