It appears to me that the problem is the Politician Voter Complex.No I think that is ridiculous, for two reasons.
First, anyone who has had ANY contact with military officers knows they need to have a bond with their men based on implicit trust and would not wish to sacrifice their lives unnecessarily, least of all for the profit of some 3rd party corporation.
Second, these corporations do very nicely out of the peacetime expenditure of the armed forces on equipment. They don't rely on wars to be profitable, nor does the military have any incentive to bankroll them artificially through starting wars.
What certainly does seem to exist, however, is Eisenhower's "military-industrial complex", whereby there is an incentive to talk up threats, propose new equipment to meet them and then supply it. But that is not at all the same as actually fomenting war for its own sake.
The people that do that, notoriously, are politicians and their acolytes in think tanks and the media, trying to push an agenda or distract from problems at home by building up foreign bogeymen and uniting the country on the pretext of these bogus threats.
Pols wage wars, & voters re-elect them.
