I have so much to say over this comment. I'll try to be concise.

remove the blockade on Gaza, give everyone there citizenship and become a secular state

• Israel doesn't trust Hamas. The blockade, which, mind you, is also enforced by Egypt, is meant to limit the group's ability to procure weapons. Water, food, fuel and other necessities are usually provided by both Israel and international help.
• Neither Gazans want Israeli citizenship, nor Israel wants Gazans to be its citizens.
• Religious and secular political forces quarrel in Israel daily. It can't just "become" secular. A big portion of Israelis don't want it to.

When has Israel not leveled civilian buildings? Have you not seen charts comparing Israeli casualties to Palestinian ones?

• If not for Iron Dome, Israeli casualties would be way higher.
• Any civilian casualties are to be condemned. Yet, you must remember that Hamas likes to base itself under hospitals, schools, mosques. Not only that, but Gaza is also very densly populated. They're some 2.5 million people over 365km squared. It's very difficult to carry out any strikes without damaging hundreds of people. Yet, in the 2021 conflict, only 260 Gazans died as a result of strikes, despite hundreds if not thousands of shellings. Israel claims that at least 200 of those were militians. If that is not surgical, I don't know what is.

I think Palestinians should be the ones who should be angry for the way Israel has treated them since inception.

Read a little about the history of the conflict, as well as about peace talks and different offers that Israel made.
