Guam, eh? It is a long-held nuke storage and bomber base (since the early 50’s), but a poor target for someone lobbing missiles from the NorK’s latitude. Even a little bit sideways, or long, or short and, “Who cares? It missed.” And, when it misses, there is nothing around Guam to get hit.
But the launch itself, and the explosion or the failure to explode, give us immediate reasons to destroy their government, military, and Kim himself.
That darn rotation of the Earth.......
