Nasrallah went all out defending Hizbullah's intervention in Syria today, vowing a "long battle" and telling the Syrian opposition that they will not succeed in toppling the Assad regime militarily.
Most strikingly, he blamed the militia's intervention in Qusayr on the Lebanese state's alleged failure to protect Lebanese in Syria. This is the same excuse Hizbullah officials are using to placate their grieving supporters in funerals of fighters killed while fighting other Arabs in Syria.
So once again, Nasrallah justifies his actions by blaming it on a weak Lebanese state, which, ironically, his group is responsible for weakening. This is a confirmation of Hizbullah's policies: By ensuring the state's institutions are weak, its foreign policy prisoner of Syria and Iran, and by denying democracy from taking its course, Hizbullah can continue to exist as a regional militia that allows itself to intervene military on behalf of Iran in any local, regional or world conflict.
But if the above is a shameless admission of guilt, it's also a desperate attempt to placate their troops and their families, by pandering to long held beliefs of government neglect and Sunni disregard for Shia religious sensitivities.
Nasrallah in his speech not only defined the US, Israel, the Arab League and the Syrian opposition as enemies, but also added the Lebanese state, which he said failed to protect Shias living in Syria and to bring back Shia abductees. He is indirectly telling his followers that their actions in Syria are not dissimilar to kidnapping Israeli soldiers and starting a war over Lebanese prisoners held in Israel.
This being an existential battle for Hizbullah, which is possibly facing growing resentment from many Shias losing their sons in a jihad they did not subscribe to, Nasrallah reverted to the good old scapegoat technique. It's the Shias vs. the rest, and "everyone else but us is to blame for our misery", which in this case, is self-inflicted. But that's not something Nasrallah will admit, though one hopes some Lebanese Shias will finally get.
