Coming due to a waning superpower near you. To the Doghouse for your elucidification:
Medicare–it provides less than half the medical expenses of its beneficiaries, the elderly and the disabled–is13% of the Federal budget. Total Medicare spending in 2009 was $484 billion. In 2009 the total interest on the National Debt attributable to military spending was $390 billion. That’s the interest we pay on all things military (including VA costs and military pensions) for having acted, since 1946, as though it were perpetually 1944.
Our ten Nimitz-class supercarriers represent a $450 billion collection of holes in the ocean in construction costs alone; they’re scheduled to be replaced by 2040 by an equal number of Gerald Ford-class hulks at twice the cost, assuming you believe 2005 estimates, which you shouldn’t. That’s construction costs. Not development, nor maintenance, nor upgrades, attendant fleet, staffing, planes, aviation fuel, or the cost someone will eventually bear to do something with the twin reactors when we don’t need ’em anymore. That’s our supercarrier Navy. No one else in the world has any. Their role is to intimidate tenth-rate military powers, since we haven’t figured out how to invade any on the ground.
Which is distinct from figuring out why we need to invade any, since that answer is either too amorphous to pin down, or too brutally self-reflective to ever see the light of newsprint.
