Except who is proposing "defense budgets [be] cut to the bone"? The answer is no one. Even under the lower funding scenario, we're still talking about a world where we're vastly outspending all potential enemies.
And we should continue to do so.
You seem to suggest that we know how much said enemies are spending...and how to calculate the amounts we are transferring to these enemies via:
1. "Bat-winged, high-flying and hard to detect, America's RQ-170 Sentinel plane is the perfect stealth drone for peering into another country's secret sites without being caught.
One was used in May to feed back live footage of the US Navy Seal raid on Osama Bin Laden's compound in Pakistan.
So probably not the sort of hardware the CIA would ever like to fall into the hands of the Iranian Revolutionary Guards Corps? Oops."

Of course, a different President might have blown it up....
and
2. "A newly released document from the U.S. State Department reveals that the most successful Chinese espionage operation in recent history occurred during the Clinton administration.
The document accuses Hughes Space and Communications Company of violating U.S. national security 123 times by knowingly sending detailed missile and space technology directly to the Chinese army."

Did you subtract the values of above from defense spending, and add it to the phantom-defense-spending of the above nations?
Atomic bomb experimentation and research didn't cost Soviet Union much, either...
And all three under Democrat administrations.....
Yes, because we know there has never been a spy craft shot down when a Republican is in office. Are you really that stupid? Also, it's pretty absurd to believe that the enemy attempting to reverse engineer something from current technology is going to really shrink that funding gap. Do you really think we don't spy on what other countries are doing as well?
While we're at it, does this mean you support withdrawing military aid to Israel, since it's well-known they take large portions of what they buy and then sell it to China.
