Republicans aren’t 'negotiating'—or, more accurately, 'extorting'—from a position of strength. Because Biden has a 'de facto' veto over their veto of aid to Ukraine.
I'd go so far as saying divert all weapons from Israel too, Hamas is terrible but Genocide is never the answer, plus Israel is really being gross currently, it's unfortunate. But Ukraine absolutely should be receiving those weapons instead. Not supporting it in any way what so ever but if Israel is going to genocide then they need to figure that shit out on their own (I know it's the govt not the people) and deal with the consequences of their actions (diplomatic consequences, I'm in no way suggesting more violence).
