US presidential candidate Ron Paul said Sunday that the CIAs drone campaign in Pakistan was making the US less safe. It makes things worse, said Paul, the Texas Congressman running for the Republican presidential nomination. Sometimes they miss. Sometimes there is collateral damage. And every time we do that, we make more enemies. Paul criticised the CIAs programme of striking at militants in Pakistans tribal areas. Appearing on Fox News Sunday, Paul said that the drone strikes threaten to provoke a civil war in Pakistan, erode Pakistani public opinion of the US and undermine American security. For every one you kill, you create 10 new ones who hate our guts and want to do us harm, Paul said. In the interview, Paul pushed back against the contention that he was an isolationist, arguing that his stances favouring free trade and more-open borders showed the opposite. But he made plain, as he does regularly, that his foreign policy stances differ from those of many in the Republican Party. Paul told Fox News that he opposes sanctions on Iran. Citing continuous reports over the last decade that Iran was close to making a nuclear weapon, Paul sounded skeptical that Tehran was about to do so. In any event, he said sanctions were not the way to dissuade Iran from becoming a nuclear state. Sanctions are acts of war. Dont put sanctions on them, Paul said. Offering friendship to Tehran could be more productive than punishing Iranians through sanctions, he said. For them to be a threat to us or anyone in the region is blown out of proportion, he said.
