The recent post-war violence in Iraq has placed Iran at the top of the Bush administration's regime change list. Reports indicate that U.S. intelligence officials are looking into a possible link - direct or indirect - between Iran and Iraqi militia forces led by Shi'ite Muslim cleric Moqtada al-Sadr.
Sadr has long been an advocate of an Islamic theocracy in Iraq and apparently has some financial ties to Iran. If this is true (heck, even if it isn't), then look for Bush to include as part of his 2004 campaign platform an expansion of the "war on terror" into Iran.
Why not? After all, we invaded Iraq over much less.
