My hubby works at PACOM, and seems to be worried about this and watching it very closely. We are leaving this island in a few weeks thank goodness!
Unfortunately unless you are moving to South America south of the equator, it won't do you much good. Below are great circle maps showing the path of an ICBM traveling from North Korea to Washington, DC. That distance is only 6,869 miles (11,055 km). The missle has a range of 15,000km (9322 miles). It can reach every place on the earth but the shaded region in the first image.
