On Sunday: https://www.nytimes.com/2024/11/17/us/politics/biden-ukraine-russia-atacms-missiles.html
The US has said no to the Ukraine using it’s long range missiles, and every other supplier followed suit. Escalation wasn’t something that would have gone over well during the election, so no one was prepared to give it the go ahead.
The general global sentiment has been that any nation being attacked should be able to do everything reasonable in it’s power to respond. While no-one wants to see an escalation to nuclear war, people also don’t like the idea that you should have to just roll over and take it just because your enemy has nukes.
The whole reason the Ukraine is in this situation is because it gave up it’s nukes on the promise they would get left alone. We want to see a world where we eventually move past the threat of nuclear war, but no one is ever going to give them up again after seeing what played out here.
My guess is, with the election lost, Biden decided that he would just let things play out, and the other nations that supply the missiles were happy to follow suit.
