In 2010, General McChryalst took a huge strategic risk, deploying 100,000 troops across Afghanistan in a nation-building effort
Well,no,he didn't. Even Generals don't make that sort of decision these days. He MAY have,and probably did propose that because he seems to have been an asshat,but the decision to go into nation-building was a POLITICAL decision.
Granted,McChryalst IS a political creature in uniform,but there is no way the professional fools in the US Congress are going to allow a mere fool in uniform to take their power away from them.
IF McChryalst had been an honorable General he would have advised his political masters this couldn't be done,and resigned if they insisted.
Since,as far as we know he never objected and never resigned,we can only assume he went along with it,which makes him both a lackey and a fool.
