Japan dispatches Biggest warship to help US

Washington: This Monday, Japan dispatched its biggest warship since World War II to protect a U.S. supply ship over the growing tensions in the region of North Korea.

North Korea has threatened to sink the Carl Vinson and a US submarine.

Following an order from Defense Minister Tomomi Inada, the Izumo will escort a U.S. Navy supply ship from waters off the Boso Peninsula, in Chiba Prefecture, to the area off Shikoku, according to the sources.

Japan is coming to US’s aid under the new national security laws formed in March last year.
It has assigned the Self Defense Forces (SDF) to escort and guard the US warships.

“Despite strong warnings by the international community, North Korea today went through its ballistic missile launch. It is a grave threat to our country. This is absolutely not acceptable. We strongly condemn such acts,” Prime Minister Shinzo Abe told reporters, as reported in BBC News.
