Are "they" preparing us for a war against Iran?

if the us does try to fight iran it will be one hell of a fight. ever since the trade embargoes against iran in the 80s i think the country has been building its own military weapons. from tanks, helicopters, planes, uavs, to different types of missiles that have a very long range. they also have about 545,000 troops, 350,000 reserves, and its paramilitary Basij that have 90,000 full-time trained active troops. iran could also call up another 11 million people for service who are part of the basij and every single one of those people will fight for their country to the end like the japs did in ww2. the country also has plans to fire missiles at enemy oil refineries to cripple sale of oil they will use those nukes.
