We are not in 1945 where the threat picture is suddenly and massively reduced with only a few large and predictable as well as stable threats out there. Massive cuts in defense as we typically do post war (and we're not done) will cause major problems for us because we are facing numerous and different threats in various regions of the world. Things are too volatile and not even intelligence can give you good predictions. We have some out there who are rapidly gaining in military strength and capabilities (technology, i.e. China). The DoD already took some large hits with the cutting of the Zumwald boat, missile defense, F22, FCS... Massive cuts that went largely unreported in a pro Obama media and where other concerns (economic or pop culture trash) dominate.
It's an even bigger "facade argument" to stoke fear by claiming that an attack is imminent if Congress cuts defense.
We have some out there who are rapidly gaining in military strength and capabilities (technology, i.e. China).
Well maybe if we made deep across-the-board cuts in most domestic programs and some sensible cuts in Defense we wouldn't be funding China's military build-up by borrowing so much from them.
