If you really think that going back to the green line would end anti-Israel sentiments in the world, you are a bit naive. We were there in 67'. We were in smaller borders in 47', and we were at the mercy of Europe in 39'-42'. This history was perpetuated by real people, and such animosity cannot end in one or two generations. If you really will get to the bottom of things you'll see that European religious beliefs cannot allow the Jews to have an independent state. Its still the notion of "Le Juif Errant" which is predominant here. If you don't believe me check for yourself: ask your Christians friends bashing Israel, if they believe that Jews living today are in any way guilty of Jesus' crucifixion. They might tell you the whole humanity is guilty or something, but probably not the correct answer "No". You might be surprised.
