Amos Oz is a noted Israeli academic, author, journalist, and novelist. He's also a vocal Netanyahu critic. More on his recent comments below.
It's well known that Israel's government reflects militarized occupation, colonialism and apartheid. It's done to enforce harshness. It continues because it's profitable. Doing so breaches international law.
The 1973 International Convention for the Suppression and Punishment of the Crime of Apartheid (the Apartheid Convention) called it state-sanctioned discriminatory "inhuman" racism.
It's "committed for the purpose of establishing and maintaining domination by one racial group of persons over any other racial group of persons and systematically oppressing them."
