I'm bringing up Hamas because they're the belligerent. The same reason I'm bringing up Israel. Who should we be talking about? Fatah? The PLO? They aren't in power.
The apartheid narrative is also a false one. Apartheid was under a racial test. It was a system of South Africa's white minority's choosing. That isn't the case in Palestine. There are millions of Arab Israelis. There were no "Black Whites" in South Africa's apartheid.
From 1948 to 1967, Palestine existed for 19 years as a presumed state. To get UN membership, all they had to do was form a government. Not a single Israeli soldier stepped foot into Palestine during those years. Then, the Egypt, Jordan, United Arab Republic (which included the Gaza Strip), Syria, Saudi Arabia, Iraq and Kuwait all attacked Israel unprovoked. Since then, Israel is at various levels occupied territories used to launch that war.
At various times, it's eased its occupation, most notably after Oslo and the 2000 Camp David conference. Palestine has held, at various points, elections with Israeli help. Ehud Barak worked earnestly on a Palestinian State. So did the international community.
Then in 2006, Gazans elected Hamas in a relatively democratic election. No election has been held since. Israel has not occupied Gaza since either, though it has controlled its radio waves, airspace, and ports with good reason.
Life in Gaza is intolerable and inhumane. The West Bank is also bad, though obviously not as dire (Israel does directly occupy the West Bank). It's a complex and sad story, with plenty of Palestinian suffering, but apartheid it is not.
