And you understand war? Not typewriter wars, but real wars? Wars that involves human beings? You can bomb a city, but you cant hold a city with bombs. You can hold a city, but you cant take over a country! A winner of a war controls infrastructure and logistics as a few key elements, and next is the people. Big Satan will always be Usa and Israel for Irani people. Good luck with that mentality. Invasion wars is difficult if you do not win over the people straight away, almost a good blue print was Iraq, but still 50% is not happy, and also why Isis became a real problem. If Irani falls, and you think Isis was bad, just wait and see, there is so many who are ready to pick up arms all over middle east, and restart what was once a new Islam state. Count the countries bombed and intervened by Uk, Usa and Israel the last 4 decades, and you will have an estimate for what will happen. Now all this countries have their people spread out all over the world, ready to finance and support, as well do a little terror here and there just to keep us busy.
