My point exactly. As you don't have an argument,... just denial.
I just ask myself, would the reverse be true? Would a successful politician make a good military leader?, and I'm afraid I can't convince myself that it would be the case.
There have been cases where retired military men were at least passable politicians, but that is the case with a number of professions. Andrew Johnson for example was a tailor, but that does not in any way support the argument that all Tailors make good Presidents.
Oliver Cromwell??
