Maybe Gaza would have a similar culture to that of Egypt, maybe Qatar, maybe Iran, maybe Saudi Arabia, maybe UAE?
Who knows what the region would be like if either or both sides made different decisions. It’s an impossible thought experiment with all that has happened in the Middle East.
You also need to understand that supporting Palestinians does not mean supporting Hamas. It’s frustrating how often we need to keep repeating this. Maybe it makes all that has occurred in Gaza more palatable to blame the victims for voting in Hamas 9 years ago.
It is also possible to look aghast at what is happening in Gaza and feel for the Palestinians without necessarily knowing or even appreciating their political views.
The value of a person’s life is not dependent on their belief system.
