Massive Defense Budget in the US does not Increase Security

The roughly $1 trillion spent on defense is eight times the defense budget of the Chinese.  Ultimately, the biggest threat to national security is our debt and global warming.  So, if we spend more on the military, and increase our debt, we get a negative security return for every extra dollar we spend on the military.   It is time to look at every program the Pentagon runs, and make some cuts.  I think we would do just fine on $500 billion, or a 50% reduction in defense spending.
