The army and air force announced plans for a large-scale exercise on the Iraqi border.
Why on Earth would Iran be exercising troops on the border with Iraq? Iraq isn't about to invade Iran. And we aren't in Iraq, so we can't invade. What the heck is the point? Is Iran trying to frighten Iraq? Preparing to invade to retaliate if Israel or America strikes Iran's nuclear facilities? Preparing to retaliate for sanctions?
A good time to review my take on the Iran-Iraq military balance. You can see why I really wanted US troops on the ground after last year.
They've gone at it before, recall.
