It was a calculated risk and they got burned. Fool me once...
It requires a change in tactics and the IDF will adapt. Of the 3 branches, the Navy is probably the weakest - only because the army and air force have had a helluva lot more practice, given that the arab navies consist of squat.
This is significant only in the escalation of weapons and obvious involvement by other powers and the brief emotional lift to the Mohammedans. The true battle impact is limited.
Israel needs to get destroyers, cruisers, etc. The Muslims are not going to have a weak navy forever.
