Plenty of people were saying it.

You haven't offered any evidence that it isn't.

In fact, Israeli ultranationalists in private conversations even welcome the comparison to Apartheid, because they think Apartheid was gentler than what modern Israel has achieved. Under Apartheid, the black South Africans could travel to white-controlled zones for work. Under the Israeli program the Palestinians languish behind 35-foot-tall concrete walls in what are little more than open air prisons with the Israelis controlling Palestinian access to power, food and water. As the thinking goes, who cares if this radicalizes the Palestinians if they are radicalized on the other side of a wall.
