those of us who support Ukraine would still like America to have a military

If not for the US/NATO, this war wouldn’t have happened in the first place.

Begging your pardon, but your reply sounds like, “oh no, don’t try to reform your party, because that’s just damage control; and don’t try to make a new party, became you’ll just send people to the old one.” At least they can try, right? It’s better than nothing?

FWIW, there are already other parties which should be filling this role. But, as some other comments have mentioned, organizing under a political party like PSL is probably the best way forward, since they aren't just focused on electoral tactics but instead focusing on the power we have as workers and as communities (the electoral system was broken long before Trump took power, it would be foolish to pretend 2027 will be any more viable than Germany's elections after the Nazi Party took control).

You have absolutely nothing of value to add to this conversation.
