ROUGH CUT (NO REPORTER NARRATION) U.S. President Barack Obama arrived in the U.S. on Friday after his historic trip to Vietnam and Japan. Obama became the first incumbent U.S. president to visit Hiroshima, site of the world's first atomic bombing, in a gesture Tokyo and Washington hope will showcase their alliance and reinvigorate efforts to rid the world of nuclear arms. Before arriving in Japan, Obama spent three days in Vietnam, a trip that underscored shared concerns about China's growing military clout as Beijing aggressively advances sovereignty claims to the South China Sea.
