I feel like she is a bit naive about that. Racism is like a really big driving force that has lead us to where we are today, and it is still a huge part of the problem. But even if you snapped racism out of existence right now, I think that specifically the Gaza situation would only slightly improve. I think there are a few really critical things that you would also need to eliminate:
- The biggest driving force in that area is religion, both Christianity and Judaism in Israel and the US (not all of them, but a lot of powerful parts of them) really want Jerusalem and Gaza as they are both important parts of the return of the Messiah if I remember correctly
- Second and very close to first is power. For the US Israel is the Middle East HQ, supporting the Israeli government is basically non-negotiable. Only if the US government changes to one with actual morals (Yeah right) will they actually go against Israel. And for Israel it is currently with a government built on corruption that leans heavily towards extreme right and religious parties.
- The rest are money, racism, and other common culprits.
I truly believe that if tomorrow racism was gone there would be very little difference in the overall situation, and this is not to reduce from fact that racism is a huge reason of how we got here.
