CAN UNDERSTAND. Firing artillery & mortar rounds across a border, aren't a "border clash". They hit Israeli settlement and started a war. They weren't mere words, they were HIGH EXPLOSIVES. Yes indeed, SYRIA STARTED THE WAR, Israel reacted. Comprehend? I doubt it. Terrorists weren't being "harbored" they were put into the field and crossed the border to inflict their death and destruction. You have two emphatic factors. artillery & terrorists both crossing the border, both overt acts of war. Good grief, you really are thick.
