Do you need to ask stupid questions? Don't forget how many people it employs. How did Bin Laden get killed? By nukes or armed forces? who rescues hostages? Nukes or armed forces? who provides support to allied nations? Nukes or armed forces? Who can be used to help in natural disasters? Nukes or armed forces? Also who combats the 2nd enemy terrorists?
nuclear weapons don't have anything to do with other arms.
no country is going to use them, so without armies, navies, and airforces, you cannot respond proportionally to small scale attacks. No nation
You have a gross misunderstanding on how armed conflict works, and a gross misunderstanding of the cold war, and its history.
Most of the military in reality is theorhetical power, to be used in combination with diplomacy and parlance. What diplomatic feats can we achieve because of the perception of our military. Not just against as a threat, but also as an incentive to be allies.
You also have to think long term. Russia and China probably won't threaten a land invasion against us. If we didn't have an Army at all, they might consider it, or it might come up repeatedly in unrelated negotions and diplomacy.
I agree, our military budget is too big. We are stuck on outdated ideas like an oversized navy, and we pay far far far too much for research and development that goes nowhere to politically connected firms.
Ironicly this decreases our actual capability to sustain a war, because the military consumes more resources for less direct benefit. It used to be the other way around. US military effeciency combined with economic might won us WWII, because the nazis had big, expensive, unreplacable machinery.
When Americans lost equipment, they just got more. The biggest thing we can do to boost our military is boost civilian industrial production of industries that in times of war can effectively make war materials, and make more efficient goods.
This doesn't fit in with the needs of congressmen than sponsor the "pro-military" politicians.
The original "Starship Troopers" novel actually talks about the matter.
When a recruit asks his drill sergeant why hand-to-hand instruction is still needed in a day of "push-button" warfare, the drill sergeant notes that dropping a nuke on any and every dissident group is like taking an axe to an unruly child: you've demonstrated that you have all the power in the situation, but at the same time, you've just destroyed anything and everything that might potentially have been saved.
Instead, nukes are a last resort for when all other methods of successfully ending a conflict have failed.
Additionally, the drill sergeant openly questioned the recruit's fitness to serve in the military if he was indeed that ready to just drop the bomb on everyone.
