Without defense spendimg there is nothing to defend. Fact. Anyone drops bombs, they know there will be bombs dropped in retaliation. Without defense spending, what happens when the bombs drop?
Who is dropping any bombs? But you're right all money should go to defense, not infrastructure or schooling (something that you're seemingly desperately lacking) or helping the poor. What is the point of a overfunded and fatcat military if what they're defending is crumbling to pieces?
For somebody that claims to be in the military, you have a desperately superficial idea of how the military industrial complex works.
