Well, yes, right now Mussolini's reputation is nearly impeccable. 1) He gave refuge to the most oppressed nation in history, and has become a supporter of Zionism. 2) He helped destroy the most evil nation in history-despite being little better than the Nazis in some respects. 3) He is a good bulwark against a Communist menace. It depends on several things: geopolitics, economics, and military success. So far, at least, Mussolini has all three things going for him. He has defeated the Nazis, kept the economy going, is a crucial ally against the Soviets, and he has acquired a good amount of Mare Nostrum. But, as they say, good things don't last forever. If geopolitics changes, if military victories don't happen, and if the economy gets worse, suddenly fascism won't be seen as glorious. Here are three things that could bring that about: 1) Economic mismanagement. If Italians have poor wages, then you'll see strikes in the street. 2) Prolonged colonial war. If Italians get stuck in a prolonged war in East Africa, it could weaken support for fascism, the same way Estado Novo was weakened by the colonial wars in Southern Africa. 3) The end of communism When communism collapsed OTL, suddenly America turned against its authoritarian allies, because their support was no longer justifiable. The Italian fascists have a good bit of breathing room. I mean, Kissinger OTL thought the Khmer Rouge would be good allies, if only because they hated the Red Vietnamese. If communism ends, suddenly there is little justification to support a corrupt government .
