Hmm this thread seems to have moved a thousand miles or so from St. Nazaire to Monte Cassino. Still I am with you on this one Tom. When other options were available, the allies became fixated on Cassino and that resulted in thousands of wasted lives/casualties.
I came across an interesting article on the 'net from historian James Holland who has written books about the campaigns in Malta, North Africa and more recently Italy. The link is below. Although focusing on the build up to bombing Cassino, the article mentions the alternative attack proposals by Major-General Francis Tuker, commander of the 4th Indian Division. Tuker also spent time discussing the possibilities of mountain warfare with General Juin, commander of the French Expeditionary Corps. Tuker's idea was to attack elsewhere and isolate the Germans at Monte Cassino.

The article is critical of General Bernard Freyberg, commander of the New Zealand Corps but the whole sorry episode is confirmation of what can go wrong will go wrong.
