Over the last few days I've suddenly become convinced that a war with Iran is likely, and is only a matter of time. News that Israel bombed Syrian nuclear supplies is part of the equation. And when the French of all people begin to speak of war, one starts to wonder when rather than if.
It will be a moral and strategic mistake to initiate a war on Iran. That being said, I don't think it will prove to be as big of a challenge for our military as people think. Iran only has the capability for asymmetric war.
