The liberal mind is too primitive to comprehend the notion that billionaires should not exist in the first place, and so their equally primitive solution is a feeble 'wealth tax'. Such is the impotency of their imagination.
I think you're underestimating the importance of a casus belli.
Even the Nazis tried to make up some bullshit lie about Poland invading Germany first to justify their aggression. It can't just be any vague threat, either; the threat needs to be immediate and credible. 9/11 made Islamic Fundamentalism an immediate and credible threat. By comparison none of the examples you listed could be leveraged as immediate or credible. Half are old news and the other half nobody cares about.
Now of course you're right that this could just mean we'll collectively ignore it all, but given there are real problems facing Americans at home I don't think foreign adventurism is on the minds of many people if anyone at all. The only possible exception to this right now might be Iran but I don't know if Americans are fully on board with yet another war of aggression in West Asia - especially not if it's one we lose, and we likely will. Even the bourgeoisie don't seem united on attacking Iran.
I don't think the "war on terror" angle is effective anymore tbh. Bin Laden is dead, the nascent Islamic State was smothered in its crib, the Taliban won in Afghanistan, the Gaza Genocide is forcing people to rethink Hamas/Hezbollah, and 9/11 was almost 25 years ago. A lot of people have moved on from that; Islamic Fundamentalism just became less and less of a credible threat over time. I also really doubt they're going to try and re-invade Afghanistan. There's basically no support for this and I doubt even the admin wants to. If we end up attacking Iran then it'd just be redundant anyhow.
Compare this with the "narcoterrorism" angle, which is closer to home and does impact Americans. Drugs remain a big talking point because the problem is persistent and local; not distant and vague.
You are right that the Venn Diagram of Zionism and anti-semitism is almost a circle, though.
The "antisemitism" break that is splitting American Fascists should be more accurately understood as a split between the cynic ghouls like Carlson and the fundamentalist lunatics like Huckabee, which in turn is part of a broader bourgeois split on Zionism - with Carlson's bloc recognizing that backing Israel is unsustainable and that the Zionist Entity is outliving its usefulness while Huckabee's bloc are 'true believers' who are too blinded by their own bullshit to see the writing on the wall.
The recent aggression against Iran is sort of a double-edged sword that benefits, yet harms, both factions. On the one hand removing Israel's biggest obstacle to dominating the region enables broader Israeli (and thus American) power projection but the existence of a hostile state in the form of Iran also serves as a 'credible' excuse for imperialism in West Asia to an otherwise ignorant public.
Removing that thorn removes Israel's restraints but also removes any justification for supporting Israel in the first place or any other misadventures in West Asia. They'd have to find a new villain and with Russia now out of Syria there's no other contender.
"International Law" is about as real as Scotland's national animal.
IL is an excuse for Western empires to topple any regime they want. Pretending it's anything more than that is as delusional as believing we can beat fascism by voting.
Comparing Vaush to Hasan is like comparing shit to dirt.
