The basic problem in war and politics is that far too many politicos, regardless of advanced rank or not, select qualified generals to run wars, and then no sooner are these generals in the field, than some political yard bird attempts to dictate tactics!
Naturally, if the plan works, regardless of the author or who's blood was left upon the field of battle, the politico takes the bows. Whereas, if the tactics are a bust, all armor-plated desk/political heroes, immediately duck for cover - let the blame fall where it may (away from them, that is)!
Naturally, even generals can screw-up, history bares this out well!
But "Political Generals" have always been a military bane!! And in this respect, little has really changed!! (opinion)
