allied disaster at Sicily & Italy

I concur with this analysis. Only extreme misfortune coupled with incompetence could cause the Allies to fail. About the worst they could do would be Anzio type 'failure'. But Anzio was at the time when entire focus of Allies has been shifted to France, while at the time of Husky and Avalanche 100% focus was on Italy. With that, there is no possibility of either operation failing spectacularly enough to significantly change events.
