In fiscal 2015, the federal government engaged in $1.1 trillion of discretionary spending, but relatively small amounts went for things like education (6 percent), veterans' benefits (6 percent), energy and the environment (4 percent), and transportation (2 percent). The biggest item, by far, in the U.S. budget was military spending: roughly $600 billion (54 percent).
China, the world's #2 military power, spends only about a third of what the United States does on the military. Russia spends about a ninth.
Brown University's Watson Institute for International and Public Affairs put the cost to U.S. taxpayers of the U.S. wars in Iraq and Afghanistan at nearly $5 trillion thus far.
Over the course of the next thirty years: $1 trillion for the rebuilding of the U.S. nuclear weapons complex, plus the construction of new nuclear missiles, nuclear submarines, and nuclear-armed aircraft. Aside from the vast cost, an obvious problem with this expenditure is that these weapons will either never be used or, if they are used, will destroy the world.
