It basically means the end of Israel as we know it. The alternative is a "two-state" solution, which is impossible due to the settlements Israel itself founded.
So let me explain my thoughts:
* Israel cannot expect to hold on to settlements on Palestinian territory.
* It is impossible to forcibly evacuate 500,000 people from their homes. Israel lacks the physical (police/army) and financial means to deal with a mission like that.
* If a two-state solution is made, and all Israelis leave Palestinian territory, Israel will be a tiny little state, and the distance from Qalqilya to the sea is just 13 kilometers. Israel will not survive a single war with the Arabs.
* Israel will hugely benefit from integrating as part of the Arabic world. Throughout the ages, Jews have lived under Islamic rule (note that this will not be the case here - it will be a secular state) for many centuries, generally with more success than those who lived under Christian rule.
I personally think they would be mad to share a state,they have survived 5 wars with the Arabs so far so i think they should stand their ground,besides they are not alone and have allies.
Israel should keep its identity and should reject a one state solution IMO,they've made a good job on their own,i see nothing in a one state solution for Israel other than more opportunities for its enemies.
The economic benefits of peace with the Arab world are huge. Trade, education, tourism, and more.
They have this already
It means the end of Israel - and the beginning of something much better.
Then its a good reason to reject it,why should it be the end of Israel,why not the end of Palestine
