[Non-Sequitur]

We could probably shoot across the coast; south east from Iraq, south west from Afghanistan, and link up somewhere in the middle.

With what? In case you hadn't noticed a huge chunk of our military is occupied right now.

The mullahs would be cut-off and their government would collapse. No more petro-dollars funding their mad dreams. The oil market would suffer a serious jolt, but would be back to normal in no time.

Wasn't that what was supposed to happen in Iraq?

"Wasn't that what was supposed to happen in Iraq?"

Well not exactly. We literally conquered the ENTIRE country not JUST THE OILFIELDS.

We actually hunted down and captured the leadership, instead of just cutting off their funding and destroying their military power.

We actually attempted to govern and enable democratic elections rather then simply weakening the government and allowing nature to take it's course.

COMPLETELY DIFFERENT
