True but trivial. What matter is not what they both necessarily had to do, but what obstacles they had to overcome, what problems they had to contend with, respectively. The hurdles encountered by Montgomery, both economical and political, were literally negligible in comparison to the ones facing Rommel. At no point during the campaign did Montgomery or any of his predecessors not operate from a position of considerably greater strength, through little effort of their own if I may add. This is literally the elephant in the room and I don't see how it can possibly be plausibly ignored.
Even if I were to accept that "At no point during the campaign did Montgomery or any of his predecessors not operate from a position of considerably greater strength" , which I don't, the fact would remain that everybody before Montgomery didn't beat Rommel.
You'd be underestimating the pressure Montgomery has on him:
He is the British General commanding the only British land effort against the Germans and everyone of his predecessors has failed.
Not to mention, what was the alternative in strategic terms?
Base off Tripoli, hit the British as he does initially while they off balance. Don't try and push into Egypt but keep mobile in the desert - fall back onto your own lines if necessary and let logistics work against the British. Don't get sucked into a set piece battle that plays to British strengths when you are at the end of a tenuous supply line and they are not.
Italian glory is not Germany's problem and nothing you achieve in North Africa will help you if you don't beat the Soviets. Every truck, plane and tank that goes to Africa takes away from that.
Secondly, what do you make of the already mentioned Hindenburg/Ludendorff? They seem to contradict your verdict entirely, as do people like Beck or Fritsch or Blomberg who, being at the highest echelons of military commanded, actively tried to dissuade the leadership from its aggressive course and even plotted to kill their CiC when they realised he was not to be reasoned with, who in short, were being politicians in every sense of the word?
H&L's record as German leaders is terrible, and rather than take responsibility for their failure they bought wholeheartedly into the "stab in the back" myth.
Both Fritsch nor Blomberg are conspired against, not conspirators.
Beck is regrettably an almost unique case.
