The following is the words of a German officer in World War II. How to understand them?

These three sentences will be better understood if they are read separately. If Italy is the enemy, we only need 10 divisions to defeat him. This article fully illustrates Germany's contempt for Italy's combat effectiveness, but it is also understandable, because Italy's combat effectiveness in World War II is really not worth mentioning. From the attack on Ethiopia, a weak African country before the outbreak of World War II, we can see that it treated such a weak country with planes, tanks and even poison gas that violated international law, and it was difficult to occupy Ethiopia. After the outbreak of World War II, under the condition that Germany had occupied Paris, France, 20 Italian divisions failed to defeat the French-Italian border defended by 8 French divisions (besides, the French capital was occupied by Germany), and then attacked Greece and North Africa, with heavy losses. Without the help of German fascists, I really don't know how Mussolini would end up. This is also the reason why the Germans despise the combat effectiveness of the Italian army. If Italy is neutral, we need 20 divisions to guard against him. This sentence mainly reflects that Italy is a wavering country. During World War I, it was obvious that Italy joined the allied forces led by Germany before the outbreak of World War I, and immediately after the outbreak of World War I, Italy joined the allied forces and stabbed it hard after the Austro-Hungarian Empire. It was after the outbreak of World War II that the signs of France's decline were exposed, and Italy quickly took advantage of the fire to declare war on Britain and France, hoping to make a fortune in the war against France. Mussolini didn't expect his army to be so flustered and vulnerable, so this sentence from Germany truly reflected the situation in Italy that year. If Italy is an ally, we need 30 divisions to defend it. This sentence also reflects the extent to which Italy's combat effectiveness is poor. A few examples can best highlight this sentence: in Africa, Italian anti-aircraft artillery units shot down the landline of their Libyan governor Marshal Gbagbo; In the confrontation between North Africa and the British army, because there was no crowbar to open the shell box, only a few shots were fired and they surrendered (it is absolutely ironic that the highest-ranking general killed in World War II was shot down by his own people); The only casualty of American landing in Sicily was a soldier who was bitten by a lion in the zoo, and so on. There were too many such jokes by the Italian army in World War II. No wonder the Germans said that the lovely Italians only knew opera literature and women, but didn't know there was a war, so later historians commented that Italy was a "poor imperialist country". Your analysis is interesting.
