“False flag” enemies have a special place in the hierarchy of crimes committed in the cover of war. This is a tactic that probably predates history, and has been treated most viciously by the targeted force when detected.
There is strong reason to believe the “Israeli” soldier that was caught and killed by a number of Gaza Strip civilians a couple days back was one of these “false flag” operatives. They are perhaps in even greater danger from their own side than from the enemy they purport to be copying from.
