Japan is apparently stumped over how to deal with North Korea, which carried out its sixth nuclear test Sunday in defiance of international warnings, political experts say.
Following the test, Pyongyang's most powerful to date, Japan agreed with the United States and South Korea to put more pressure on the country, following the same pattern used to deal with past provocations by North Korea.
The experts, however, say North Korean leader Kim Jong Un will not abandon his policy of pursuing weapons of mass destruction unless the continuation of his regime is accepted by U.S. President Donald Trump.
