P.S. I asked myself:

Can an Israeli and a Palestinian communicate linguistically?
in the german wiki it says about Israel:

The Israeli population forms a culturally diverse society in which a number of languages are spoken. According to the Israel Central Bureau of Statistics, there are 33 languages and dialects in Israel. The most commonly used languages are the official language Hebrew as well as Arabic, ...

In a way, Israel then would be to Palestine what Austria and Switzerland would be to Germany, no?

Where would peace be the best solution, other than in these closely neighbouring countries?

To see if you can trust your government one indicator would be if the language of the neighbor is being forbidden as just naturally spoken or where actions can be detected that the language shall be eliminated from the public realm.
