I suspect that you are spot on correct with that statement, sir.
As many have stated the Israeli Navy is really the ugly stepchild. They really haven't been involved in any major engagements since some 1973 battles with the Syrians near Latakia.
I susoect this was due to carelessness and some initiative on the part of Hezbollah.
It's happened to us as well. The Iraqis and the Taliban have shot down a bunch of Apaches and Blackhawks. A good number of Abrams Tanks and Bradleys have been taken out by the insurgents due to IEDS and other munitions. In Gulf War 1 a few jets were shot down. The NVA and VC shot down quite a bit more than a few. To expect to fight a war and have no materiel losses or dmages is really unrealistic. Hezbollah night het a few IAF planes as well. I certainly wouldn't be shocked.
That's what war is largely. The bad guy adapts and you react. The ship seemed to make it back to port of its own steam. The damage appears to be less than the Cole for example. I suspect they'll learn from this and move on.
