Every faction is Israel has many national heroes. An Israeli rightwinger would be furious that you list did not include Jabotinsky, Begin, Shamir, Eitam, or either Netanyahu. And Sharansky too. The astronaut's name was Col. Ilan Ramon, he also flew the bombing mission that destroyed the Osirak reactor, which was followed by Begin's famous "Never Again" speech. Kodratos, are you a Sabra?
No I'm not. I was going to add for comedy's sake Yigal Amir. I can't believe I forgot Ze'ev Jabotinsky though. Begin was cool, but I don't think he is really a "hero". Netanyahu is a personal favorite of mine. I would like to see him replace Sharon.
P.S. Are you Jewish? What branch do you follow if so?
