Taking issue with dictatorships that have nuclear weapons or we *know* are developing them is a far cry from invading a country thinking they might have some vague program to create WMDs.
And while yes the Patriot Act is still in effect, I'm bet good money that Obama will let it expire when it comes back around or will kill it in a few years. In his short time in office, Obama's made a point to reverse alot of Bush policies. Just cause he ain't done yet doesn't mean he's the same.
