Ukraine support polls at over 60%, Israeli support polls similar - heck even Fox News has admitted this. The only issues pop up when items are intermingled, as support for 1 doesn’t necessarily equal support for the other.
One of the biggest issues is not support, but how the Biden administration has approached both conflicts. Americans want to see wins, so far the Biden Administration hasn’t articulated how Ukraine wins and what is being done for that.
The same goes for a number of other theatres.
The problem looks something like what Jerry Pournelle used to mention, one iteration of which was this one:
"If we want Gaddafi dead, tell Delta Force to go do it. If that is too drastic, then just what should we do? A long time ago Allard Lowenstein said to me about Viet Nam, "You want to win it and get out. I just want to get out. But McGeorge Bundy and the Johnson people want to lose it and stay in." I do not want Libya, Afghanistan, or Iraq to be places where we lose it and stay in."
All places people "stayed in", and ultimately lost. (What happened to Libya afterwards cannot be accounted a "win".) Anyone learn anything yet? Not the Democrats; they have a long tradition of throwing away hard-earned results after doing just enough to keep things going until the public got tired enough ("war exhaustion") and the political cost of throwing away the "win" became negligible. Not the neo-cons; they're still bellicose and incompetent imperialist wannabes, and re-electing Trump would be a small price (accounted world-wide) compared to the "broken windows" cost avoided by keeping them away from the White House.
Ukraine is looking like a place where its international backers are willing to do enough to keep it going, but not to win it. So just get out now. And if no-one's going to fix the Houthi problem at the source without dragging it out, just get out and go ahead with "routing around the damage".
I reiterate that both the Democrats and establishment Republicans are responsible for the decades of flushing treasure and lives down the drain without much to show for it. And now that practically everyone (as in, nations) has spent themselves into severe debt, with large deficits, exactly how the heck does anyone expect to intervene?
Meanwhile, I suppose all the would-be troublemakers have noticed that "The West" has gotten way out over its skis in domestic spending commitments (certainly true for US and Canada) and is quickly draining capabilities without ramping up replenishment. Over-spending has some pretty far-reaching consequences.
