Prime minister Shinzo Abe is trying to keep Donald Trump on side, but the Japanese people are watching with worry

Since the end of the second world war and the enactment of its pacifist constitution, Japan has deployed its forces overseas mostly on peacekeeping operations under UN auspices – and almost never to places where its troops are in harm’s way. But next month, the country will send a naval destroyer to the Middle East. On what is being described as an intelligence-gathering mission, the warship will patrol the Gulf of Oman, the northern part of the Arabian sea and a portion of the Bab el-Mandeb strait, following a series of attacks on oil tankers in the region – including one that was Japanese-operated.

In 2015, Abe passed unpopular legislation allowing Japan to exercise the right of collective self-defence
