Why Did Israel Let Mengele Go?

All this talk about how Israel's intelligence agencies were turned to the task of Palestinian terrorism without a single mention of why these palestinians, an occupied people on their own land, might resort to force.

Then there's the almost gloating tone they took to the planned murder of a 12 year old boy, justified by "jewish blood will not be spilled with impunity"

I wonder if the author will take the same attitude when Palestinians assasinate an Israeli soldier in retaliation for the countless airstrikes and starvation campaigns conducted against the palestinian bantustans.
