The best way to remove the corrupt governments in Israel and Gaza are to ensure the stability of that region and empower the people to vote.
Over 50% of Palestinians in Gaza are under the age of 18. The last election there was in 2006. As a result, the regime in control was not voted on by the people. Without an end of the war, and stabilization, both of these monstrous regimes, the Israelis and extreme militant Hamas members, Palestinians will continue to be collectively punished.
The goal should not be to destroy Hamas, but to ensure that the people living in Gaza are empowered to make decisions about the leadership. Similarly, Israel needs to shift leadership because they are participating in a modern day genocide that endangers Israelis and Palestinians, and creates instability in the region.
