What you may be missing is under Clinton there was actually a 2 state solution agreed upon by Israel. Arafat refused to sign it stating “If i did, i will be dead by morning”. the Palestinians do not want a 2 state solution. Do you know what “From the river to the sea” means? It is the genocide of the Jews.
Making book availability age appropriate is not the same as banning a book. However, if any state is actually really banning a book i would not agree with it.
If no one said it, how can you say they have it? They were ready to sign, you may look it up if you care to.
