In all likelyhood, yes. That's the most frustrating part of all this. The Republicans are the ones pushing isolationism, relative to the Democrats.
Shit like this is generally beyond left vs right though. It's the realpolitik shit that the whole world runs by.
As I stated in the other site, one's political ideology isn't a simple two-axis system. I'd argue there's a third one - populism/nationalism vs. globalism. Trump is a right-populist, someone like Bernie Sanders is a left-populist. The thing about populists is they don't conveniently fit into the two-axis shit we use to describe someone's political ideology. Right-populists, for example, are willing to have socialized healthcare, as long as that money goes towards citizens and not immigrants and gibbers. Same for welfare.
Populists will actually be generally anti-immigration, even from the left wing side, because they will see it as a threat on the working class (the left wing view) or the safety of the nation/economic damage (the right wing view).
Populists are fine with protectionism, regulation, tariffs, etc. as long as those things favor the population over corporations and overseas interests. Tax breaks for corporations that bring their production back to the original country. Special treatment for companies that encourage a country's ideals. Less sending our shit overseas and more doing everything ourselves.
Trump isn't going to drag the entirety of the US into a war. He's just taking advantage of the fact that Iran can't do SHIT against us. Iran has no air defense now. Russia is occupied with Ukraine and is actually losing, and China would be fucking retarded to retaliate against us as that will ultimately be a Mutually Assured Destruction scenario.
So yeah, whether through accident or intention, right now Iran has been put in a no-win scenario. Notice how we keep blowing up their shit and all they can do is have a temper tantrum and attack Israel instead?
And before it looks like I'm simping for the Jews, my initial view is that we stop fucking funding Palestine AND Israel, but as long as the Jews got Iran by the balls and foreskins, targeted airstrikes with NO boots on the ground is fine. Not ideal, but fine.
