1. As to debates on and condemnations of Israel, the important thing is not what is said about other nations: it is about whether what is said about Israel is true. Bringing in the treatment of other nations in no way affects the truth or falsity of judgments about Israel. 2. Security concerns are irrelevant when their purpose is to defend an unjust situation. The Union of South Africa had legitimate security concerns defending their apartheid government which championed white domination. That was irrelevant because its security concerns were there to perpetuate injustice.
