The failure of the U.S.'s foreign adventures often seems to have its roots in the U.S.'s total ignorance of things on the ground, of the countries that they fiddle with.

The great thing about using the past is that it gives you the most colossal freedom to invent. The research is necessary, of course, but no one writes a novel to dramatically illustrate what everybody already knows.
