Obviously you have been to a very peaceful school. Look, in the schoolyard it is always the weakest kid who gets dragged behind the bikeshelter and has the crap beaten out of him by the school-yard bully. In this case that is Syria. This is far more realistic than an attack on Iran - while the US could easily beat the Iranian army, take the post-war operations in Iraq and multiply the problem by, uh, a lot. Iran's male population that could be called up to serve is almost as large as the total population of Iraq, and three times the service-age population of Iraq, 4.5 times that of Syria. Landmass is almost four times that of Iraq, ten times that of Syria. Borders with lots of countries that are problematic in the case of Iran, only with US Allies in the case of Syria.

Syria is to Iran what Arnold Schwarzenegger is to Woody Allen. I know who I would like to take on, even if I am Mike Tyson.
All the best
