The situation which developed in the UN-observation zone now has in the past caused a lethal bombing of a UN-bunker by the IDF before. In an demilitarized UN-zone between Lebanon and Israel Hisbolah fighters misused that area and took cover in the vincinty of an UN-observation post. The UN-soldiers there by their mandate could only observe and report, what they did. They were not allowed to fight the Hisbolah. Fully informed IDF dropped a bunker-breaking bomb on the UN-bunker, which solved the problem but caused collateral damage (4 UN officers dead, among them an Austrian major). There is a strong collective memory among the Austrian troops of this incident. The same situation has developed on the Golan now: the zone is not respected as demilitarised by illigal fighters anymore. They already take adventage of the free zone and could again misuse an UN-post for cover easily because they know the UN must not shot at them. Imagine they brought rockets with them. Would the IDF not react again in a similar was by taking the cover i.e. the UN post out with a smart bomb claiming later it was misguided? So: Not Austrian chickens but bad experience! One would be a bad leader not to pull out of a siuation where one only can lose.
