What are you talking about? Iran didn’t have to fight us by sending insurgents to Iraq. The Bush administration set up a new Iraq govt composed of Shiites who’d been living in Iran to get away from Saddam. And the new constitution explicitly said sharia law comes first. That’s what our 4000 troops died for. And it cost the U.S. more than $1 trillion
It should have cost us nothing. Iraq had the oil funding that could have reimbursed every penny of the war cost, plus rebuilding their infrastructure, plus funding our veterans care.
That’s where Bush screwed up IMO.
Those IEDs in Iraq, they came from Iran. We did absolutely nothing about it.
It is true that the leadership was favorable to Iran, but Iran didn’t like the U. S. in there, and wanted to cause our efforts to fail.
