Great idea.  Look at the roaring success of US intervention in the middle east; 

Afghanistan is, yet again, ruled by warlords and criminals, with the Taliban knocking on the doors to power...just like 3 decades, hundreds of thousands of lives and trillions of dollars ago...before the US decided to back anybody who opposed the Russians...the mujahedeen, who became al Qaeda and isis.

Iraq;  The US was besties with Saddam for decades so Saddam thought he had the green light to invade Kuwait.  Well, not so fast, and more hundreds of thousands of lives and trillions later, it was Iran that had to push isis, (remember them?), out of Baghdad and Iraq.  

How about US's Saudi proxy war with Yemen?  Poorest country in the region, supposed to be over in a couple of weeks, thousands more lives and more trillions later....

....and the list goes on....but Iranians are the bad guys.  

Rrrrriiiiigggghhhhhht...!

So after a seeming endless string of failures, you want to take on Iran next.
