Comment: Insane McCain at it again wanting to spend billions on foreign wars. McCain is a sad spectacle, bitter and angry, a sour grapes loser who can never be president.   Senator Paul is correct. The USA needs to withdraw from most of these foreign entanglements that we pay for. The country is $20 trillion dollars in debt. McCain and Graham  never met a war they did not like and thousands of Americans have died because of these two and their war mongering.  McCain needs to retire with dignity and enjoy what time he has left.
