Even more fundamentally obvious, the number of toys and troops, and their vast overarching deployments, creates an atmosphere that inevitably leads to wars. This is opportunity presenting itself to the military, and wars of opportunity. Let alone how it benefits the military industrial complex to have our military in such positions of opportunity.
If we have troops deployed globally, as we do now, the likelihood of elective war, even global war, goes up exponentially. It's what keeps such military geopolitics sustainable. In short: Weapons have a tendency to go off. It's what defines them as weapons. The idea of a deterrent force is an oxymoron and a myth.
