Washington - President Donald Trump said on Tuesday that "all options are on the table" in terms of a US response to North Korea's launch of a missile over Japan.In a terse, written statement on Tuesday, Trump said that with the missile launch North Korea has "signalled its contempt for its neighbours, for all members of the United Nations, and for minimum standards of acceptable international behaviour.""Threatening and destabilising actions only increase the North Korean regime's isolation in the region and among all nations of the world," Trump said. "All options are on the table."In a first, North Korea on Tuesday fired a midrange ballistic missile designed to carry a nuclear payload that flew over US ally Japan and splashed into the northern Pacific Ocean, officials said. The aggressive launch over the territory of a close US ally sent a clear message of defiance as Washington and South Korea conduct war games nearby.‘A grave and growing direct threat’Trump and Prime Minister Shinzo Abe of Japan conferred by telephone over the latest missile test and how to response.The White House said on Tuesday that the leaders agreed that North Korea poses "a grave and growing direct threat" to the United States, Japan, South Korea and countries around the world."President Trump and Prime Minister Abe committed to increasing pressure on North Korea, and doing their utmost to convince the international community to do the same," the White House said.Abe said in a statement that "Japan's and the US positions are totally at one."The prime minister added that both nations were in "total agreement" that an emergency meeting was needed at the UN Security Council to step up pressure on North Korea after what he called an unprecedented threat. He also said Trump expressed his "strong commitment" to defending Japan.North Korea's latest test came weeks after the UN Security Council voted unanimously to impose tough new sanctions against the government in Pyongyang.It also followed a series of missile launches late Friday, and came after a period in which the US and North Korea had traded heated rhetoric over Pyongyang's continued missile tests, which violate UN Security Council resolutions prohibiting them.Trump last week praised North Korea's decision to back down from its earlier threats to attack the US territory of Guan."But, Kim Jong Un, I respect the fact that I believe he is starting to respect us," Trump said at a campaign rally last week in Phoenix. "I respect that fact very much. Respect that fact. And maybe, probably not, but maybe something positive can come about."Secretary of State Rex Tillerson also had complimented North Korea for its restraint in recent weeks.
