Yup sounds like a jew defense. . . for their roll in terrorism. . .

The IZL [Irgun Zevai Lemui] executed Jews suspected of informing, even though some of these persons were totally innocent.

In order to kill the greatest number of soldiers, without taking risks oneself, nothing could equal electric mines. Made to look like milestones, they contained fifteen kilogrammes of explosives, which we made ourselves from common chemical manure (ammonium nitrate). To this we added five to eight kilogrammes of bolts as shrapnel. A curfew having been established on all roads from nine o'clock on, we left every evening in groups of three to place our mines at the edge of some orange-grove. A wire, fifty yards long, connected the false milestone to a little detonator. A push on the button was enough to blow up a truck.
Leaving aside the fact that they face, and that they had the unpleasant experience of seeing their transport interfered with, the English lost tens of dead, and suffered innumerable wounds, without ever succeeding in capturing one of the girls or boys responsible. Records were set up for losses inflicted with a single mine; I believe it was held by Lea, the wife of Dov, with thirteen killed.
