Securing our own country does not necessarily mean we should reduce our military budget. Preparing "for the worst", quote unquote, can require the use of extensive spending as there might be a need to protect against an attack by another country: this means we need to keep our military shipshape.

Although the spending that the US has on its military is the largest in the world, only a small percentage of the government's total expenditure - about 4% of the GDP - is spent on the military. Although the spending was growing exponentially in previous years due to overseas engagements in Iraq and Afghanistan, the spending is currently - and predicted to continue to drop in the coming years.

As for the varied uses of the spending, it is spread out among many uses. Among these are funding for the: Department of Energy, Department of Homeland Security, the FBI, NASA, the Treasury Department paying pension to veterans, the State Department, federal and local law enforcement, and Veterans Affairs. The US also uses its military spending to develop new technologies and supplies that may help our allies or our troops in any future engagements or that we can sell for a profit.
