Trump first insulted war hero Sen. John McCain for being a POW. Now he is attacking General John Allen (a four-star marine general who commanded the war effort in Afghanistan) as a "failed general." This latest insult directed towards yet another distinguished combat soldier is in direct relation to Allen endorsing Clinton at the DNC convention. For a man who aspires to be commander in chief, and who has never served in the military, and who has no children serving, this new insult is a window into his mind and his complete lack of leadership skills.
