In 2001, the US demanded that the Taliban hand over Osama bin Laden. Had they complied, we would not be at war with them and they would be in control of Afghanistan.
In 2003, the US demanded that Saddam Hussein allow UN weapons inspectors to search for WMD's. If he had complied, he would still be alive and in power.
Both the Taliban and the late Saddam Hussein are worse off as a result of their defiance. A skilled politician could argue that our military has succeeded in dealing out retribution to our enemies and it is time to bring our boys and girls home.
