Iran has supplied devices that killed our soldiers.
Iran has invaded our embassy in Iran and taken hostages.
Iran has threatened to assassinate our leaders.
Iran has/is bombing our allies.
The ayatollahs have to go!
Iraq harbored and assisted the original Ayatollah Khomeini and his extremist followers, precisely because the Iraqi government wanted to use Khomeini to destabilize Iran.
Then Iraq took in Abu Sayyaf and his followers.
Then Iraq aided the head-chopping Islamic terrorists in the Philippines.
Then Iraq took in the guy who arranged to meet up with two of the future 911 hijackers in Kuala Lumpur, who were attending a planning session to bomb the USS Cole in Yemen.
Then Iraq took in Zarqawi, the founder of ISIS, who ran a smuggling route through Iran, Iraq, and Syria, and allowed him to set up shop in Baghdad with a bunch of Egyptian terrorists, more than a year before the US invasion.
And of course both Iraq and iran were involved in all of this, because the enemy of their enemy is their friend.
Not feeling sorry about thumping Saddam and his Baathist buddies or about thumping Ayatollahs and their minions.
