im sorry if I offended you. But every since Israel was established in 1948, all the wars it particpated in was only because it was attacked first, and i will prove it. Ah I found it. This site shows all the wars and gives a little bit of info about them. I was a bit off as it seems that israel did attack in some of them, but If you look into the summary of those wars you will see y Israel reacted the way it did.
