Obama vows to go 'toe to toe' with rogue nations

Democrat Barack Obama cast himself Saturday as the leader the United States needs for it to stand up to and engage renegade nations such as North Korea. "We need a president who'll have the strength and courage to go toe to toe with the leaders of rogue nations, because that's what it takes to protect our security," the Illinois senator told Democrats at a rally. "That's what I'll do as your next commander in chief." Obama and rival Hillary Rodham Clinton have had a running argument since clashing in last week's debate over how far the United States should be willing to go in its diplomacy with countries such as Iran, Syria, Venezuela, Cuba and North Korea.
