NBC News is reporting that the U.S. military is preparing for a pre-emptive military strike against North Korea if the nation continues with a test of a nuclear weapon.

Such a strike would be the show of strength from the Trump Administration against a nation that has crossed lines the U.S. has warned against.

We do not know at this time when/if North Korea will test a nuclear weapon, or when/if the U.S. will strike a nuclear target. However, it does appear that the U.S. has moved naval forces capable of launching Tomahawk missiles into North Korea should the need arise.

We’ll keep you updated.
