This book starts with a definition of apartheid as specified in the International Convention on the Suppression and Punishment of the Crime of Apartheid in UM General Assembly Resolution 3068. Then the author compares the similarities and differences between the apartheid policies in South Africa and Israel.
This book extensively documents Israel’s discriminatory policies against non-Jews — by-pass roads, land theft, illegal Jewish settlements (illegal according to international law), travel permission slips, checkpoints — to name just a few.
If you want to understand the root cause of the conflict in occupied Palestine, the first book I recommend you read is “The General’s Son” by Miko Peled. The second book I recommend you read is this book, which you can get from this store or that store.
