But the posters over there and seemingly at MINIMUM half the country do not hold actual beliefs.
Whats good = what Trump says is good
A perfect example is with the Iran war or military conflicts in general: Trump and Vance called themselves the "pro-peace candidates," and expressed how they weren't going to get the US into any more wars. So, some people voted for Trump at least in part under the (incorrect) belief that Trump wouldn't start military conflicts with anyone. Fast forward to Trump threatening to invade Greenland, abducting the Venezuelan president, and starting a war with Iran (that is explicitly called "a war" in the MoU, so no one can deny its war status). Some outspoken MAGA politicians and media or Internet personalities expressed their dislike for the US-Iran war, or Israel's part in the conflict, and were ostracized, ridiculed, and insulted by the MAGA base at large. Some posters in USPG2 said they didn't vote for a war with Iran when they voted for Trump, and their posts were immediately dumbrated and they were shit-talked.
There can be a world where a presidential candidate honestly campaigns on not starting any new conflicts, but then an adversary declares war on them. There would be many factors involved, of course, but in that case one can honestly say they wanted peace, while others had different plans. That's not what happened here. Trump withdrew the US from the JCPOA in 2018 without replacing the agreement. This whole US-Iran war is an attempt to have a nuclear deal to replace it after peaceful negotiations failed. The current MoU makes "a lot" of concessions, as admitted by MIGA congressmen, just to get Iran to agree to some kind of nuclear deal similar to the 2018 deal. Trump and MIGA criticized Obama's JCPOA deal with Iran, and are now acting like they're going to get something better.
The main issue for the US is that there won't be a better deal on the US's side. Iran didn't surrender, didn't beg for mercy, and isn't making many (if any) concessions. Iran showed the world that the US can't bomb an enemy into unconditional surrender as Trump originally demanded, or even into a US-favored conditional surrender. It's the US that is giving in to Iran's terms to make this happen, and Iran is constantly pushing the limits and demanding more. Iran is leveraging its nuclear program and its illegal control in the Strait of Hormuz to get as much as possible out of the US, and it's not failing. Just look at the plan for $300 billion for the development of Iran. This isn't a situation where Trump would be the savior of the world if Iran agrees to not further enrich uranium, because it would just be a return to pre-2018 status. So, is that actually a good deal?
MIGA won't criticize Trump for any of this. They won't criticize him for withdrawing the US from the JCPOA without replacing the agreement. They won't criticize him for demanding an unconditional surrender and then failing to get it. They won't criticize him for threatening to destroy the Iranian civilization, and then not following through. They won't talk about his violations of the MoU signed days prior when he threatened the lives of the Iranian delegation. All of that is fine to them. None of that goes against their beliefs, because the only thing they believe is that Trump is right. They try to claim that people like the posters in this thread have TDS whenever anyone brings this up, but they use straw man arguments and irrelevant topics to deflect from actual criticism. They'll do, follow, and justify everything he does, no matter what it is or how costly it is to the American people. Whatever "Make America Great Again" was, it died long ago and became "Make Israel Great Again," and MIGA is cheering it on while calling us the traitors.
