Really?,thats funny because I cant think of any countries that iran has invaded and destroyed or governments it has overthrown unlike the us actions in the region,now as for irans missiles I can only think of two,perhaps three countries where they are located,you have iran of course and syria produces the fateh 110 under license as the m600 and possibly lebanon,altho as yet there is no evidence of the transfer of these systems ie guided missiles apart from the usual unsubstantiated israeli claims,so technically there are no iranian missiles in lebanon just short range unguided rockets,so you have at most 3 countries with iranian missiles,perhaps 4 if you throw in the very small stocks of short range antiship cruise missiles that the houthis probably only received after the saudis with us support started attacking yemen,and 2 of those countries only received short ranged missiles ie 300kms range,so its pretty far from "all over the region",in addition iran has only ever used its missiles in anger once since the end of the iran iraq war,last month to be exact with perhaps 6 fired in total,now how many times in the same space of time has the us used its forces in anger?,well quite a few to put it mildly.Now by comparison we see that the us in addition to its bases and occupation forces in the region has supplied at a minimum tens of billions of dollars worth of various types of high end weaponry to multiple client states thru out the middle east,so its pretty obvious that there is little comparison between irans missiles and the us supply of weapons regionally and the same can also be said for the costs of irans real politik vs us actions in the region.
