Novelist Andrew Klavan, in this video, notes that people are consistent. After the Holocaust, everyone said they would 'never again' stand at the sidelines when Jews or other people were being annihilated. That's quite true, he says - this time they're helping.
Commentator John Rosenthal provides a graphic example, describing how the European Parliament received the Israeli ambassador to the EU. One or two Members defended him; the rest accused Israel of various heinous crimes, and refused to believe that the video he showed of the flotilla incident could be real.
The group these Europarliamentarians are defending so vehemently makes no secret of its goals. The leader of the group states quite clearly that his goal was jihad. As jihad includes the annihilation of the State of Israel, I can only conclude that Andrew Klavan is right.
