I agree completely that Hezbollah makes up a huge problem, and after their involvement in Syria there’s not a hint of legitimacy left in the organization if there ever was any.
But one would do well that to remember their origins: They are what’s left of the resistance from the last time Israel invaded Lebanon. So that’s what a great fucking success that was.
And Hezbollah are not Lebanon. They control territory, and they need to be fought, but this in not how one fights terrorist organizations. This is how you create terrorist organizations. Which is exactly what Israel did the last time they invaded.
