Suicide bombers don't make it terrorism.

Were the Japanese Kamikaze pilots terrorists? No--their targets were clearly military in nature. Likewise, was the US pilot that kamikaed a terrorist? No. (His plane had no hope of making it back to the carrier, he could have bailed out but the only possible rescue would be from the very fleet he was attacking. No path with a meaningful chance of survival, as soldiers in hopeless situations often do he chose to take as many enemies with him as he could.)

Terrorism is about the target, not the means.

All in all, Israel is doing most of the killing here. They have access to more sophisticated weapon, but it's no less barbaric.
