The difficulty is that the UNRWA welfare fraud that supports two Islamic terrorist franchises is an endowment that the Arabs-Moslems occupying the disputed territories are not going to give up.
Why would they risk losing their welfare if the alternative is having to work for a living?
So, why doesn't Israel end the occupation so that the Muslims and Christians will lose their endowment?
What "occupation" would that be?
I'd like to ask "why do the competing franchises of Islamic Terrorism Intl., Inc., continue to further acts of Islamic terrorism. But that's just begging the question.
That question has been answered since about 635 CE when the ravings of a desert Arab warlord who invented a polytheistic "religion" was unleashed upon humanity. That monstrosity of a politico-religious ideology endures today in such fascist documents as the Hamas charter.
If there is no occupation, why withhold the vote from people under Israeli rule? What other first world nation does that?
The people in Israel have the freedom to vote. It's a simple concept but I can understand your difficulty with simple concepts. You should do a bit of research on that. Do a search with the term "Israeli elections".
While you're doing that homework assignment, do a bit of research regarding the elections in Gaza'istan and Fatah'istan.
Let us know what you find regarding elections in those Islamic paradises where the typical Islamist
Dictator for Life has been a staple there as elsewhere in Islamic backwaters.
That seems pretty standard in Islamist third world locations.
