>>508431788Isis was a stupid little terror group that took over portions of Syria, Iraq and some oil pumps. They single-handedly got every western state to install concrete blocks at every shopping centre and fucked things up for a decade.
Iran is a nation with a fully operational arms industry and lots of mountains and hidey holes. Not to mention an intelligence community, pull in Islamic affairs, multiple proxies, and a deal with Russia and other naughty states to keep its economy going despite efforts to fuck them. They simply just shoot down ships in Hormuz and tell all their little goat fuckers abroad to start blowing stuff up while funneling terror supplies to anyone that will take them (with China and Russia helping because fuck the west)
