By easing tensions with Cuba and now Iran, President Obama is recklessly squandering Americas precious supply of enemies, the leader of a conservative think tank said on Tuesday. Our adversarial relationships with Cuba and Iran took years of frostiness and saber-rattling to maintain, Harland Dorrinson, the executive director of the Washington-based Institute for Infinite Conflict, said. Thanks to the President, decades of well-crafted hostility have been thrown out the window. According to Dorrinson, fears abound in conservative circles that the President might be capriciously casting about for other powder kegs to defuse during his remaining time in office. If his shameful record is any guide, hell probably try to disarm North Korea, Dorrinson said. Thats the doomsday scenario. Regardless of his future actions, Obamas detente with Cuba and Iran will likely tarnish his legacy forever, Dorrinson said. On this Presidents watch, America lost two of its most enduring foes, he said. Hes going to have to live with that for the rest of his life. Watch: Life as an aspiring standup comedian.
