I do know the defense budget has always been obscenely huge. With the end of the cold war I was hoping that money would be put to more socially enriching purpouses but Oceanian perpetual war against terror (war against a method rather than a nation state) has replaced it now to the great releif of the pentagon and military contractors i'm sure.

As far as being a threat to the economy, I know that here in So.Cal the military/industrial/aviation/aerospace industry WAS THE ECONOMY is many of the suburbs here for many decades.
