While I'm with you on the idea that the country refuses to face the enemy, you can rest easy about TWA 800. The detonation was caused by a design flaw in that model of plane. The gas tank would become unstable under a confluence of factors, like temp/humidity, plane angle, weight, how much gas was in the tank, etc.
It all happened to come together that day.
I konw it seems too simple what with the plane having come from Athens and Navy missiles in the area and all, but Murphy and Occam say the most likely answer is the most likely.
