Israel began breaking the UN resolution the day it was enacted with flyover incursions into Lebanon. On several occassions Israeli aircraft made mock attacks upon United nations land and sea units, who complained and said that they would retaliate if these activities continued. As for disarming, it would be foolish for Hizbollah to disarm unless Israel likewise disarmed, since Israel is dedicated to assasinating Nasrallah and has sworn, in the past, to wipe out Hizbollah.
