Recently, Pyongyang has been alarmed by the United States deployment of the THAAD missile system in South Korea in early March. Do people hear him saying that military force is likely to be used or that the US has other diplomatic tricks up its sleeve?
"It would be risky for Mr. Trump to let overconfidence and bombast, expressed in tweets and public statements, box him into some kind of showdown with the North's ruthless leader, Kim Jong-un, who has displayed similarly macho traits, " The New York Times Editorial Board said on Monday. The parade in Pyongyang, the capital of North Korea, featured various weapons, including 56 missiles.

"If you think that war is possible with a given state, you're going to be trying to prepare the battle space for conflict".
It is not yet known if the missile was carrying a nuclear device or a conventional warhead.
Most US dignitaries go even closer to the North Korean side when here - to a set of blue buildings called conference row that spans the MDL and allows them to actually step foot in North Korea. But some of those restrictions merely put in place United Nations sanctions passed a year ago with China's support - before Trump took office.
