In view of the very well-known facts, asking such a question is just silly. However, the Italians were NOT "cowards" - just practical and sensible, unwilling to lose their lived in a "Cause" which was no "Cause" at all, and which they had been drawn into by a ridiculously ambitious "Leader".
Their pilots, in obsolescent aircraft, flew repeatedly to attack Malta and the Malta Convoys, their submarines and Motor Torpedo Boats were very well-handled - and their "frogmen" truly remarkable ! A couple of them put two British battleships out of action in Alexandria Harbour, and others carried on a "surveillance operation" on Gibraltar from a sunken ship just outside the harbour.
We - and especially the Russians - should be very grateful for their "lack of enthusiasm" - their extreme unreliability as allies forced Hitler to divert large forces to North Africa, to unnecessary conflicts in Greece and Yugoslavia, and then to Italy itself - the Russian "victory" at Kursk only came about because of the Allied landings in Sicily and Italy, and the precipitate Italian surrender..
