Why are the yanks pussy-footing around? They're usually much more hawkish.
Because they're using Ukrainians to grind down the Russian military, and economy, by attrition. The goal isn't to "win", the goal is to destabilize Russia. Ukrainians are just ammunition. The longer the war drags on, the more costly it is for Russia.
The reason is that the US are shit-scared about Russia thinking the US is trying to invade by proxy or something.
Russia already thinks that. That's what turned the civil war in Ukraine in to a proxy war between NATO and Russia.

Okay, so? I could match that if I flipped over my couch and counted the loose change. All of the baltics together add up to one medium-large urban area.
It's the US which has gazillions of Abrams sitting around doing nothing but collecting dust and is not shipping them over, not Europe.
That would be very expensive, and I'm not even sure the US has the logistical capacity for it. Plus seeing Abrams burned out by modern ATGMs would seriously harm the US's reputation for military invincibility. And, again, they're primarily concerned that Russia loses. Ukraine winning would be a nice bonus, but it's not the chief goal.
