Honestly it seems like the only thing Trump's base cares about is the price of gasoline. They don't give a shit about what's actually happening in the war.
From the MAGA folks I know, they don't even care about the price of gasoline. That was when Biden was president. Now they have excuses. All they really seem to care about is whatever they're currently told to care about by the administration.
Trump has a loyal hardcore, but he is absolutely bleeding supporters around the edges. If you follow the US right many of them are pledging to vote democrat in the midterms as a protest.
I noticed a wave of that right as trump declared war (declared conflict, whatever), people going "I voted for no new wars," but I noticed on /r/conservative that the takes quickly gave way to sudden concern about Iran's nuclear capability as the propaganda mills got their fodder in order.
r/Conservative is, IMO, almost 100% guaranteed to be majority bots and the most hardcore admin apologists. They're a permanent safe space and often will delete even their own members' posts if they directly criticize the Leader.
Its only value is to see the desired responses from Fox News and the far-right media.
Who moderates /r/conservative? Whenever I drop into old subreddits these days the whole place feels very astro-turfed. High chance that it's modded by zionists, they have a lot of money and a lot of different organisations that hire full time people to "fight disinformation".
The war machine is already rewriting this as Iranian hostility.
The base is incapable of seeing this as a failure of their cult leader.
Instead they'll see it as the very rationale and justification of the war.
If they were ambivalent about it before, now they'll scream bloody murder for even more off-the-leash barbarism from the US and Israel.
