U.S. President Barack Obama on Tuesday called for renewing and bolstering the U.S.-Japanese alliance as both countries marked the 50th anniversary of a security pact. "America's commitment to Japan's security is unshakable, and our cooperation to meet common challenges is a critical part of our engagement with the world," Obama said in a statement released by the White House. "And just as we honor the countless Americans and Japanese who have built the ties that bind our nations, we also look to the future with a determination to build upon the foundation of their progress," he said.
