But Ukraine was already provided guarantees- including not being invaded by Russia and if they were we would aid them explicitly - when they agreed to give up their nukes.
And look where that got them.
The idea that anybody but Ukraine gets to decide when enough is enough is ludicrous. They were freaking invaded and occupied since 2014. They are bleeding the Russians and Russia can't continue this for much longer relatively speaking.
It is weird to me that We the People aren't always on the side of fledgling nations in the face of tyranny.
