The Pentagon has prepared a plan involving a B-1B heavy bomber attack against the Democratic Peoples Republic of Korea which is ready should President Trump, as Commander in Chief of the U.S. Armed Forces, decide to order an attack, NBC News reported.
USA defense and national security officials have repeatedly touted the capabilities of the US missile defense shield over the last several weeks, in the wake of a pair of successful test launches by North Korea of its latest intercontinental ballistic missile in July.

On Tuesday, Trump warned North Korea not to make any more threats against the United States.
President Donald Trump again stepped up the rhetoric against North Korea on Thursday, saying an earlier threat to unleash "fire and fury" on Pyongyang if it launched an attack was not tough enough.
"And we work very closely with allies to ensure that this is not unilateral either ... and of course there's a military solution", Mr. Mattis told reporters en route to meet with senior leaders in the technology sector in Seattle and California.
Trump has said he would not allow Pyongyang to develop a nuclear weapon capable of hitting the United States.
On Thursday, Mr. Mattis declined to comment whether he was taken aback by Mr. Trump's harsh rhetoric.

'The current situation on the Korean Peninsula is highly complicated and sensitive. "He would lash out militarily, at a minimum against South Korea", Admiral Stavridis said to NBC.
