Many people mistakenly think that building a huge military was to defend ourselves. The idea is absurd -- Canada or Mexico attack US? The former are peace-niks and the latter are ragged savages.
Our leaders knew long ago what path we were on. They knew we would have a collapse and that only a military dictatorship would keep the country together. This goes all the way back to Lincoln building a huge military to crush the Soutn in an illegal and immoral war. It was concluded long ago that the people are unfit to rule (which is probably true).
With a huge military and the technology now at hand, we will have an absolute dictatorship with absolute and total surveillance. Electronic feudalism is the future.
