"If a missile targeted Guam or flew over it, we would have shot it down," US Assistant Secretary of State Susan Thornton said at a briefing for foreign journalists.
Reporters asked Thornton why the US does not respond North Korea's missile launches, which violate the airspace and allies — Japan and South Korea.
Thornton recalled that this issue was previously cleared by US Secretary of Defense James Mattis.
She noted that now it is possible to determine exactly where the rocket will fly and where it will land. According to her, in Japan there are special alert systems for the civilian population.
"The question of whether or not to apply military actions depends on specific situation," she said.
Earlier in the day US State Secretary Rex Tillerson stated that the United States would continue diplomatic efforts to resolve the North Korea crisis, but is not ruling out military options.
US President Donald Trump has recently signed a new executive order expanding sanctions against Pyongyang, threatened to "totally destroy North Korea" if immediate threats emerge and described Kim as "Rocket Man."
North Korea was quick to announce that it may conduct another hydrogen bomb test in the Pacific. Kim accused Trump of exhibiting "mentally deranged behavior" and threatened him with a harsh response.
