Iran certainly isn't Iraq,...and the global implications of a full blown war there are much greater than they were in Iraq. Also, in today's model of warfare,............we never ever leave.

Sanctions are an act of war in case anybody was wondering. I don't see the justification in starving millions of people to will a signatory to the NPT to cease uranium enrichment.

Even if Iran were developing a nuke (which all of our intelligence agencies say they are not) why would that be something that should concern the US?

Aren't we chasing them towards a weapon with all the saber rattling and the fact that we now occupy countries on the eastern and western borders?

Isn't anyone the least bit bothered by the fact we are even considering preemptively attacking a country that has not attacked us?
