"The military-industrial complex of the US refuses to realise how dangerous and volatile the world has become." I believe they are fully aware.
In fact, they fuel the volatility which is seen by the MIC as opportunity. The MIC and their supporters generate and perpetuate conflict (opportunity) in order to create a market for their consumable products (munitions, etc...). Bankers are all too happy to finance it.
