Russians won. 6%. Anyway, if you think Ukrainians, under Russian assault, are balking in any way from US aid thinking about what % of it they will eventually have to repay, you're insane.
They already lost UK size territory. When can they get it back? They are luck if Poalnd doesn't want Lviv back.
Why asking joining NATO to poke the bear? They can surrender like the French and Poles, waiting for US to send in the ground troop, or maybe not. IDK what they are thinking.
