Hello there American Administration is trying and pushing toward a peace deal between Abbas and Israel which will then might bring arab states who don't have diplomatic relations with Israel to sign peace deal and official admission of Israel as a state.
I think any peace will fail because Israel is signing deals with leaders whose first concern is to rule and to stay on the grand chair, what I mean is that if todays arab countries presidents do like Israel, tomorrow might bring leaders who hate Israel and might even go for a war with Israel because todays arab leaders have been humiliated and destroyed mentally and militarily by Israel many times.
Also, the strongest factor that will make Peace impossible is Islam because Palestine is one of the holy places to muslims and there is a god promise in Quran that muslims will enter the Holy Mosque in Jersalum as they did before.
So as long as there are those who are religious, Israel will never live in peace and generations after generations will try to kill or attack etc
Also most of arabs do hate Israel including christians and many arab countries suffered because of Israel war machine.
I believe Israel within few years might find itself in a war with Hezbollah after Hezbollah revenge and Iran is developing their militarily seriously and working toward mastering nuclear technology which can be converted into WMD technology and cause a conflict.
It is possible that within the next half century that we will see a nuclear war between Iran and the World.
Some suggested that those who came from Europe and places all over the world to live in houses of other deported palestinians to go home and every land goes to it's owner and then jews live with muslims in a country that every land goes to it's owners.
Muslims have lived with jews and christians in Palestine for a long time in peace until Zionists took over with force and taken houses of palestinians.
If jews emigrated to Palestine without using force or anything gradually, nothing like that would happen but there will not be a jewish country.
some claim that israel is for jewish people, actually many emigrates are not jewish, there are russians and ukranians who emigrate to Israel for finding a job and stuffs.
This is a reasonable solution but has many concessions that Israel must do
the second solution is that one country prevails, means there is no palestine, there is israel or reverse because religious parties in palestine will never admit Israel's right to exist and will use force and terror to serve their goals.
