WHY ARE WE IN THESE WARS?

WHY ARE WE IN SO MANY WARS?--WHY DO WE EVEN NEED WARS?
Because our Military Brasses Need Something To Do: Remember, they were trained for wars--without wars, what are they suppose to do? Sit behind their desks, eat dough-nuts and drink coffee. Plus, the contractors and sub-contractors to the Military need to sell equipments/products to the Military; so they lobby the President--they tell the President that they provide thousand of jobs, contribute to the National economic prosperity and our Nation's bank account/revenue coffer.
Now--what role does the President play in all this?--Well, when these Military Brasses hold their briefings/meetings with the President on National Security and the status of other Nations/countries military-- threats to the US and world security, etc; they tell the President what military engagements are needed; and -- 9 times out of 10-- our Presidents will do what the Military Brasses want;  why? because our Presidents are too afraid to say NO to these Military Brasses --so they signed on to these Military engagements/wars. When will our Presidents learn to say "NO" to the Military Brasses ?? .
