Correction, the election that gave Hamas power was 17 yrs ago, half the population of Gaza is under 18. Half the population of Gaza was not even born yet when the last election took place.
If memory serves, that’s also around the time Netanyahu was funding Hamas. Your post blames children who couldn’t vote for Hamas more than the PM of Israel who was funding them.
Hopefully this helps you relate more to the children and young adults in Palestine who had no say in their either.
