U.S. Vice President Mike Pence today reassured Japan of American commitment to reining in North Korea's nuclear and missile ambitions on Tuesday, after warning that U.S. strikes in Syria and Afghanistan showed the strength of its resolve.

Pence arrived in Tokyo from South Korea, where he assured leaders of the "iron-clad" alliance with the United States. He also warned the reclusive North, which has conducted a series of missile and nuclear tests in defiance of U.N. sanctions, that the "era of strategic patience" was over.
