MAGA has always been isolationist, which means unwilling to go to war for any. There is still a large chunk of Republicans who are pre-MAGA (e.g. neocons, Reaganites, globalists in the Eisenhower mold), It should also be noted that the “Christian Right” supported Trump, but is also pro-immigration (in part since many if not most of the immigrant wannabees are religious Christians) and they also tend to support Israel. Also remember that a large amount of the Democrats are now pro-Hamas, and they appear to be on the verge of taking over the party, but for culture war reasons are unable to ally with the MAGA populists. Given the impossibility of a MAGA-WOKE alliance, the DINOs (e.g. Chuck Schumer) and RINOs (e.g. Ted Cruz, Mike Pence, etc.) could either take over one or the other party, or form a third party alliance.
Trump’s base is unlikely to give up on MAGA over a muscular foreign policy, and by making an “example” out of Iran, Trump will seriously improve his, and America’s, position vis a vis Iran’s allies (Russia, China, Cuba, North Korea, etc.). The Zionists have never trusted a goyish state, and probably know how to act in their own interests (e.g. make their large bombs that can destroy Iran even if they would prefer the Americans do their work for them). Right now we appear a lot better off than in the 1930s and early 1940s, so everyone should relax and stop checking YWN every five minutes to see if the world is still there.
