Trump is right when he says that his Iran war isn't like Iraq

Trump's current war in Iraq is, of course, nothing like the Iraq war. The US won the Iraq War, quite easily. There were problems in maintaining control of the country after this victory, of course, but even these were only moderate. Over a long period of time, they were significant, though. In Iran, in contrast, there isn't the slightest possibility of achieving victory. Iran is a superpower, whether the US chooses to acknowledge this fact, or not. The entire power of the US military combined, including all possible ground troops, could not defeat Iran. The US would probably have to triple the size of its military to do this. And, there isn't the slightest possibility of that happening. What, Trump's Iran war is somewhat like, is the War in Vietnam -- an unwinnable war, with no endgame, at all. However, it's rather worse than the US invading Vietnam following the Gulf of Tonkin incident in 1964. It's rather more like if the US had invaded communist China following the Gulf of Tonkin incident, in 1964. Now, they could have done this, of course, it might even have made a certain amount of sense. After all, China was Vietnam's chief backer, along with the USSR, so taking out China would kill two birds with one stone. China was, like Iran, an up and coming world power, developing nuclear weapons. So, why didn't President Lyndon Johnson decide to attack China? I think the reason was quite simple. He didn't want to bite off more than he could chew. It seemed possible that he could defeat Vietnam, a small, but formidable country. As it turned out, he couldn't do it, and neither could Richard Nixon, but, they couldn't really know this, at the time. There was no possibility of the US defeating China, a nation of 600 million people developing nuclear weapons. The Congress would never have supported it, he would have obtained no funding, and would have gotten precisely nowhere, in any case. And, that is precisely the situation currently. The Congress won't give him the money to proceed further, and he is getting nowhere. On the contrary, the Iranians are having a terrific time shooting up the entire region, shutting down its economy, and massively disrupting the entire world's economy. The question is, as Trump indicates he is "almost done", will the Iranians stop? Why should they?
