Hezbollah is tolerated and being hosted by the Lebanese government. Lebanon allows this militant group to operate out of its territory, and so is responsible for their actions. Lebanon has clearly been warned as of last summer. If further attacks come from Israel's northern neighbor, then the whole country risks an onslaught (not just Hez locals). It is about taking responsibility. Good luck Lebanon, and I hope that you make the right choice. Disarm them.
