Iraq, the so-called Arab Emirates on the western side of the Persian Gulf, all those countries and regions ending with "stan," and extending all the way to Georgia and to this day still Farsi speaking Ossetia were not too long ago part of Iran. In the long run - not tomorrow as we're accustomed to - Afganistan and much of Iraq would be better off back in the Empire.
If ISRAEL - you know, the country the rest of the region has a mutual interest in hating, gets nukes everyone else will want - oh, wait, they've had them since the 70s but it's a secret so skip the false fear and Pakistan is a far greater danger to its east and west.
WWIII is not breaking out in the ME or Central Asia, that's just silly, and certainly not over this. Can't rule out war now because we're dealing with 2 sets of idiotic megalomaniacs: Trump & and the Ayatollahs. But full scale is doubtful, more like lobbing a couple of missiles at soft targets unless Trump is truly that out of it and the military goes along. In which case the enemy within is a greater danger to us than a broke irritable heap of has beens dwellling on glories of 2600 years ago. Tanks? Planes? Ships? pffffffft, all they have is missiles they got from North Korea. The only thing Iran is a danger to itself.
70% of the grain the USSR consumed came from the USA. We could of ended them in under 2 years by pulling that plug. Sure, they might have pulled a Germany and invaded the rest of Europe, but that still wasn't gonna get much more grain in their bakeries.
The Cold War was a fake war. 1984, that allegory about the USSR? Hogwash, it was about the whole world divided into 3 powers that utilized the same bs to control their people with eternal fake wars and propaganda. THAT'S what the Cold War was.
Since that ended, guess who we've been drafting as the new bogeyman?
HINT: Rhymes with "Iran"
Four decades, and Iran hasn't done crap yet except get one of their generals killed because, um, something.
