This is from an economic stand-point. The Journal argued (very successfully) that the problem of the US's survival later on is not going to come
from its great expense on the military (4% of the GDP) but on its even greater expense on welfare programs (as much as 10% of the GDP).
If the US needs to cut funds it should cut Welfare funds and promote military funds to provide a proper military for the US.
The National Debt, Social Security and Medicare are the growing expenses. Natioanl Defense isn't the big cause, but unnecessary wars are quite the
vacuum.
The war in Iraq is costing a great deal of treasure and just wait for the sequal.
