To be gained is a full on butt load of money by the defense industry of the United States.....not to mention the economy as a whole. War generates insane profits for a nation (that wins). Take a look at defense budgets in between wars...they are tiny..compared to the budgeted spending during a conflict..esspecially an open conflict like the middle east.
