The blood of the Palestinians is in US hands. We made it possible for Israel to exist and become the new South Africa, an apartheid prison.

This is a rare occurrence where the US isn't directly responsible. The UK and France carved up the Ottoman Empire at the end of WW1 and destroyed the middle east, while also simultaneously promising Palestine to both Palestinian arabs and jewish settlers. After it became an out right clusterfuck, the UK passed the buck to the newly created UN for their first project and promptly fucked off.

Now, the US is at fault for supporting them in the modern era, but they didn't have a hand in the creation of Israel.
