The UN can bolster all it wants of its peacekeeping forces, but the UNIFIL will never have what it takes to pull the trigger. Since 2006, the UNIFIL forces have simply been a cash-cow, with the motto: See Nothing, Hear Nothing, Say Nothing and definitely Do Nothing.
So now the IDF is doing something and intends to drive the Hizzybillies north of the Litani Mason Dixie Line. And while they are at it, give a clear message to Iran to stop messing with that sliver of a land called Israel. Iran is approximately 75 times larger than Israel, by geographical area. Or also said, Israel is 1.33% the size of Iran.
