Isn't Hezbollah A Terrorist Outfit?

It is argued by many, especially the Lebanese, that Hezbollah is not a terrorist group. It's a political party, that they're Lebanese people, that they work in Lebanese government, that they have ministers in Lebanese Parliament...

Isn't it a fact that almost all terrorist organizations in the world have backing from some political party or the other. And invariably many have their people in the Government. If because of these an organization does not become a terrorist outfit, then there are no terrorist organizations in the world. Consider Taliban; it is also a very strong political party and earlier had its people in the Govt. and from 1996-2001 they WERE the Afghan Government.

And if the issue for the war between Hezbollah and Israel was a Lebanese one, something that Lebanese govt. itself stood for, then why was Lebanese army missing in action when a foreign military invaded its territory, leave alone bombing its towns?

The UN Security Council Resolution 1559, of September 2004 calling for the disbanding of Hezbollah’s fighting force and the extension of Lebanese government control over the entire country, goes to establish and attest Hezbollah's true identity as a terrorist outfit.
