Low information Americans seem to rely on emotion and a little bit of guilt rather than logic when it comes to McCain's alleged expertise about the Military. McCain is a graduate of Annapolis and became a carrier pilot. He was shot down in Vietnam and spent the remainder of the war as a POW. How did he become the spokesperson for the use of Military forces in Syria? His opinion is no more valuable than any other politician.
To piggy back, military experience is not immediately indicative of some better understanding of current military plans. This is particularly true when considering he was a pilot – someone that is not associated with the actual strategy of war whatsoever.
More importantly, experience gives a person weight until you evaluate his opinions/voting record/council. McCain has given me all I need to evaluate what his opinion is worth. He advocates war and torture (scary when you add what he has been through) and completely counters freedom with a good portion of the bills that he backs. I don’t care if he was the Dali Llama before entering senatorial service – his opinion is worthless.
BTW, his time on the security council in the senate is worth FAR more than his military service in this case. Not that matters either as I have said above. His voting record and opinions have already invalidated whatever his credentials were.
