thing about iran is its a proper country with a proper army, navy and airforce that can cause a world of pain to anyone who tries to invade, even the once mighty america.just a few months ago they tested one of their new toys, an anti-ship missile faster than anything we have in the west. we're talkin iraq death toll times 30 at least, even then their good friends russia and china might take umbrage at said invasion and start supplying them with even more serious weaponry. it just wouldnt be worth it, in any sense of the word
