From Rep. Paul's statement:

I rise in reluctant opposition to H Res 560, which condemns the Iranian government for its recent actions during the unrest in that country. While I never condone violence, much less the violence that governments are only too willing to mete out to their own citizens, I am always very cautious about “condemning” the actions of governments overseas. As an elected member of the United States House of Representatives, I have always questioned our constitutional authority to sit in judgment of the actions of foreign governments of which we are not representatives.....I have admired President Obama’s cautious approach to the situation in Iran and I would have preferred that we in the House had acted similarly.

I adhere to the foreign policy of our Founders, who advised that we not interfere in the internal affairs of countries overseas. I believe that is the best policy for the United States, for our national security and for our prosperity. I urge my colleagues to reject this and all similar meddling resolutions.

Unsurprisingly, he was the only "no" vote on H. Res 560.

Also unsurprisingly, the nuances of Paul's consistent constitutionalist and non-interventionist position on foreign policy, and the potential dangers of an atmosphere in which other nations democratic bonafides are being "supported" in any way by the U.S., are missed utterly over at Wonkette.
