If the war continues it will all depend on whether other countries are prepared to support Iran and for how long. There are numerous similarities between the present US–Iran war and the US–Vietnam war I don't have time to list them all but a quick google will show some of them what is clear is this I turning into a war of attrition Iran is not surrendering and is striking back I'm sure the economic damage is far worse than Trump could of imagined if he even gave it a thought at all. During the Vietnam war air defences were destroyed planes were destroyed but they were replaced. North Vietnam and the VC were being supported and supplied by the Soviet Union & China without them becoming directly involved. The same could happen again. Iran is a large country with a population of 90 million Israel is a small country with a population of 10 million, without America backing them they are fairly insignificant and they're not exactly on the best of terms with their neighbours. I don’t doubt most of Iran’s air defence has been destroyed and their missiles and drones depleted but they can be replaced so can air defences. I’m sure countries like Russia, China, North Korea, Pakistan would love to know just how well their air defence systems work against the latest American weapons, the feedback and data would be invaluable. Pakistan shares a 600-mile border with Iran, at the moment its walking a tightrope doesn’t want to upset the USA Saudi/Gulf States or Iran but both Iran & Pakistan are Islamic Republics and if they are forced to choose, I feel sure they would side with Iran. Iran has the expertise to build more missiles and drones if building them in Iran proves to be too vulnerable, they could move production to another country. Ukraine for instance is manufacturing drones in the UK. Trump has opened a whole can of worms and its going to be a lot harder to put the lid back on. It’s very hard to see any benefit at all for the US in all this. The only country that stands to benefit is Israel. There is a large Jewish lobby in the US and the UK as well. Perhaps Netanyahu and the Jewish lobby persuaded Trump it would be a good idea. Personally what I'm hoping is for the US to withdraw and Trump can boast about how he won a war. The reality is the war will not have been won Iran will massively rearm and Israel will be even more vulnerable. It wouldn't even surprise me if Iran directly attacks Israel or supports clearing the West Bank of Israeli settlers most likely by proxy but could assist with missile strikes etc. Anything to make Israel pay especially if Iran feels they have the right to operate the same way the IDF does with total disregard to collateral damage or the lives of innocent civilians. I would also expect Iran to carry out assassinations like the IDF does in retaliation, Netanyahu has to be top of the list. Next time the US will want to stay well clear now they have a better idea of the consequences there is nothing in it for them.
