Many people will fall in the trap, Iran isn't a country, it's a shia theocracy with no borders, it actually expand to irak, syria, lebanon and parts of yemen and other various countries...
at least the geographic distribution of the future terrorists will be smaller
.
it doesn't mean it will not hurt less...
If the crusaders are smart, they will first push the sunnis on the war for them to take the first brunts of the battlefield, and like a nasty mafia boss, wait the moment the battle is won (ie way before the actual end) and push with all it's might, devancing the sunnis forces, to prove them what is the west about
.
In the hope that with the complete defeat of the shias, they will not think about going west again !
and for that, it will have to be extreme.
