President Donald Trump said it’s not “inevitable” that the US will wind up in a war with North Korea over its continued development of nuclear weapons, but that military action remains an option. “Nothing’s inevitable,” Trump said in a news conference on Thursday at the White House with the emir of Kuwait, Sheikh Sabah al-Ahmed al-Sabah. “I would prefer not going the route of the military, but it is something certainly that could happen.” He declined to say whether he’d accept a nuclear-armed North Korea that can be successfully deterred from using atomic weapons. A senior administration official later told reporters that the US will not allow North Korea to extort or threaten the world with its nuclear program, and that the administration is not sure the country can be deterred, Bloomberg reports. The Trump administration is seeking to ratchet up pressure on North Korea after the country tested what it claimed was a hydrogen bomb on Sunday.
