Horten,
Where exactly did Rommel “blunder”? He lost a war of attrition against the British. Monty took no chances. He had the time and the resources. Rommel knew he had to win fast in Egypt before American production tipped the scales against him. Once that occured, he knew the war was lost.
Reviewing the desert war, both sides had their share of tactical mistakes. Little did Rommel know at that time, Hitler and his top brass considered Africa more as a diversion rather than a serious front. It kept the UK/USA out of Europe - temporarily. Anything Rommel needed or requested was 2nd to the Eastern Front. Hitler, on more “sane” days, initially never considered Africa more than just “helping” their Italian Allies. A purely “political” decision. Only after it was too late, did the Reich understand Africa’s true importance. Soon after, the vaunted “Afrika Korps” surrendered.
Rommel learned his first lesson of Hitler - the intentional sacrifice of German soldiers. Hitler’s orders were to fight to the last man, delaying a European invasion as long as possible. Good strategic sense. Bad for the possible thousands of lives that could have been lost for nothing. Luckily, the German commanders in charge did surrender against orders.
After wars lines are re-drawn and cities re-built. But all that is really accomplished is that many lives are lost. In this case, because of one madman.
