Re: the Apparatus is much bigger than the US Gov
The apparatus is self-feeding and self-sustaining too.
A good example here would be the operation of said apparatus in Eastern Europe and ex-USSR in the 1990-es and 2000s. The wall, fell, mission accomplished, right?
Yes, but if mission is accomplished, then that means that agent Doe is without a job and all those precious kiddie college funds are at risk. So what does agent Doe do - continue as if nothing has happened financing any and every possible lunatic on the Russian periphery as well as recurring "regime change operations" in ex-Soviet block countries. Rinse, repeat until it backfires in the face, then more some.
Forever war is essential in feeding the monster and it will take an economic and/or political crisis of proportions USA (and other western nations) has never seen for it to be dismantled.
