Mitt Romney gave his first foreign-policy speech in Charleston, S.C., on Friday morning, the 10th anniversary of the beginning of the war in Afghanistan. He said, "This century must be an American century. In an American century, America has the strongest economy and the strongest military in the world." He did not offer specific details on his plans for Afghanistan, but did promise to conduct a full review during his first 100 days in office to determine "the presence necessary to secure our gains and successfully complete our mission." His other priorities include rebuilding the Navy fleet, redeploying aircraft carriers to pressure Iran, and setting up a national ballistic-missile defense system. Romney also said the U.S. should work with the United Nations when appropriate, adding, "While America should work with other nations, we always reserve the right to act alone to protect our vital national interests."
