So I am going to answer the LBJ attacks. First, he suffered from Cold War syndrome. Yes, Ike stated the military was bloated, and the war industry was bloated, but given how much the US spent on the military at that time, it was pretty obvious. Plus he overthrew Iran's democratic government which has led to problems to this day. (somewhat, some of the blame goes to rural Shia Muslims in Iran who have nothing better to do than oppress women under their religious elders) LBJ also loved his advisors, and US advisors back then were pretty good, but they weren't gods, and LBJ wasn't out of touch and was pretty open-minded. He should have taken a heavier leadership approach.
JFK made too many enemies, LBJ didn't make enough, and MLK made just enough to get him killed. It wasn't the safest time to be even somewhat soft on the commies.
As for inflation, we are handling it better than most countries around the world which yes may be due to the US's geography with its vast resources and NAFTA, but it's also due to BIdenomics and free trade (minus China, and a few sanctioned countries). The US could have easily been another Japan, but it didn't due to immigration free trade, and general openness.
Again with Israel Biden is not a butcher he just can't control his allies, less people complained when the Saudis under both Obama and Trump killed hundreds of thousands of Yemenis through direct(bombings) and indirect means(sanctions), and Biden ended that. He's doing what he can, and he and the DOD are likely having a yelling match with the Israelis over this.
