US Prepared to Use Force on N Korea ‘If We Must’, Says Nikki Haley

The United States cautioned on Wednesday that it was ready to use force if need be to stop North Korea's nuclear missile programme, but said it preferred global diplomatic action against Pyongyang for defying world powers by test launching a ballistic missile that could hit Alaska.

US Ambassador to the United Nations Nikki Haley told a meeting of the UN Security Council that North Korea's actions were "quickly closing off the possibility of a diplomatic solution" and the United States was prepared to defend itself and its allies.

One of our capabilities lies with our considerable military forces. We will use them if we must, but we prefer not to have to go in that direction

She urged China, North Korea's only major ally, to do more to rein in Pyongyang.

Speaking with his Japanese counterpart on Wednesday, US Defence Secretary James Mattis underscored the "ironclad commitment" of the United States to defending Japan and providing "extended deterrence using the full range of US capabilities," Pentagon spokeswoman Dana White said in a statement.

Mattis' assurances to Japanese Defence Minister Tomomi Inada came during a phone call to discuss the North Korean test, the statement said.

Taking a major step in its missile programme, North Korea on Tuesday test launched an intercontinental ballistic missile that some experts believe has the range to reach the US states of Alaska and Hawaii, and perhaps the US Pacific Northwest.

North Korea says the missile could carry a large nuclear warhead.

The missile test is a direct challenge to US President Donald Trump, who has vowed to prevent North Korea from being able to hit the United States with a nuclear missile.

He has frequently urged China to press the isolated country's leadership to give up its nuclear programme.

Haley said the United States would propose new UN sanctions on North Korea in coming days and warned that if Russia and China did not support the move, then “we will go our own path.”

She did not give details on what sanctions would be proposed, but outlined possible options.

The international community can cut off the major sources of hard currency to the North Korean regime. We can restrict the flow of oil to their military and their weapons programmes. We can increase air and maritime restrictions. We can hold senior regime officials accountable

The United States might seek to take unilateral action and sanction more Chinese companies that do business with North Korea, especially banks, US officials have said.

China's UN ambassador, Liu Jieyi, told the Security Council meeting that the missile launch was a "flagrant violation" of UN resolutions and "unacceptable."

"We call on all the parties concerned to exercise restraint, avoid provocative actions and belligerent rhetoric, demonstrate the will for unconditional dialogue and work actively together to defuse the tension," Liu said.
