Cliff Notes Version:
Iran sponsors and creates terror acts around the globe.
They perform these acts to lessen intl pressure.
They are getting the bomb.
They will use it or give it to a terror group.
There is an undercurrent of civil unrest in Iran
We either have to attack in a military fashion or create civil unrest to overthrow current .gov.
Anything that happens from this point on, still has this as a caveat... Iran is dangerous to global security.
