He sounds like all of those Dallas Seminary guys that were predicting the end during the first Gulf War. Their search for elusive relevance in all the wrong places like Pat Robinson and Falwell in politics just makes it harder to warn about preparedness for the end times. Missler becomes the straw that breaks Ice's back in the debate with DeMar.
My prediction is that the end will come when everyone has pretty much given up the idea that the end is near.
I think that Missler is over-committed about one interpretation of the nature of the so-called one-world government, and because of this, is possibly wrong about a one-world currency. (A one-world economy doesn't require a single currency.)
The one-world dictatorship isn't necessarily so, since the "kings of the east" do exist and do appear to have separate control of their armies.
