Some nitpick back. Israel receives equipment from the US, yes, but what you failed to mention is once the Israeli's have it, they modify it themselves. The Israelis have the capability to develop and make their own weapons and have from the start. They designed and built their main battle tank as well as their rifle. It's just easier for them to buy aircraft, and then modify them to suit themselves as well as standard NATO ordinance. I don't think an American pilot could get into an Israeli F-16 and fly it. It is heavily modified by Israel as is just about everything they buy. Which leads to the next nitpick. Israel buys weapons from the US. You could say that the US gives them aid, that they use to purchase the weapons but the weapons are still purchased.
Now let me answer your question. Your question is irrelevant. There is nothing in the question that can be compared. If Israel were committing genocide, then they would have to attack the West Bank and Jordan, and there would also be no refugees to feed. If Hamas was armed in the same way as Israel they would be trying to bring about a Genocide in Israel. They have said as much in their own charter. With that being said the reality is one should never pick a fight with someone you can't beat. Hamas is insane for picking a fight with an entity that could wipe them off the face of the earth, the fact that they haven't done so yet, is also proof there is no genocide going on.
