Diplomacy is a big lie costing way too much perpetuated by incapable not wanting to work a normal public service job and scaming in all side to have access to wealthy lifestyle under the pretext of representing their nations... Only diplomats are merchants.
Yes, let's fund war profiteers and undertakers instead.
Now about your bullshit of occupation? Are you mad... Where did you read it? Come, win and leave. Once hashed enough there will be no worries... I don't care about your little way of thinking. Splash it, break it, kill them enough to not even be able to surrender but just being happy to have survived and done with this regime.
Iraq was supposed to be a cakewalk too. 5 days and $50 billion. In and out in no time. With over a decade of sanctions and a devastated economy how much work could it be really? Then hundreds of thousands or maybe over a million dead from fighting and effect of sanctions. Over a decade later see how well it all turned out? How stable the region is now that iraq is a shining example of western nation building? Imagine doing the same to a larger country with more than double the population. And in an area already so unstable and with nearby strong countries that would probably intervene. At least isis would be happy to be rid of iran.
Demonstration of weakness never help. Diplomats want to always perpetuate status quo...
So just kill them instead right? It is not anyone you know so who cares?
