The situation is not like Apartheid in South Africa.
In Apartheid, the white minority controlled South Africa, and did things like denying the black majority the vote.
In contrast, Israel has a ~20% Arab minority (excluding Gaza and West Bank). The rights of that minority are respected. Arabs can vote in Israel, and in fact there is an Arab party in the Israeli parliament.
Gaza was largely self governing until the Oct 7th attacks. Israel has not shown any desire to "rule" Gaza.
