Im not sure it works exactly that way. Chairman O has weakened our military to the point theyre nothing like they were when he took office. Hes done this by PC (climate change, homs, women in combat etc etc), humiliating our military numerous times on an international stage, running off good officers replaced by those unquaified to run a war, prosecuring wars in name only, training with enemy militaries so they can get first hand knowledge on how we operate etc. Were beatable now even with a govt who isnt playing games. That and our economy couldnt sustain a protracted war. If Barry leaves office on schedule the damage is done of many years into the future. Our enemies know this and when they think its feasible attack.
Most of the damage to our military is quickly reversible. I have had access to enough information, including direct observation, to know that (1) Obama has tried to destroy our military in the ways you mention and more ways, and (2) the pathetic loser in our White House has to a large extent failed.
