Could UNIFIL fail in a way that is any more epic a fashion than their current crash course with uselessness? Increasingly, the answer appears to be not really, no:

Syrian arms smuggling serves two purposes: (1) it destabilizes the anti-Syrian Lebanese government by funneling weapons to the AQ soldiers who have been fighting the LAF (2) it stocks Hezbollah with weapons in preparation for this summer's war.

Of course, this isn't really a UNIFIL failure if you have the right frame of mind about UNIFIL's mission. It's true that they're not really doing much when it comes to stopping arms smuggling. But they are fantastic human shields for Hezbollah. So in a way - a way that the vast majority of UN nations seem to endorse - they're actually succeeding quite nicely.
