Why Western “experts” on Hizbullah cannot predict its response

"...And I am equally confident that if any committed observer is asked “will Hizbullah really respond to Israel’s attacks on Monday?” he or she will tell you that as the first such attack since the end of the July War in 2006, Hizbullah has no choice but to respond, irrespective of how deeply mired it is in the Syrian conflict and in safeguarding Lebanon from terrorist infiltration. It has to respond because confronting Israel will always constitute the larger part of its raison d’etre, even if its mission has expanded over the years. And it will respond because to not respond would upset its doctrine of deterrence and “balance-of-terror” with Israel which it painfully earned after two decades of blood and sacrifice. Hizbullah will respond because there is no precedent of Hizbullah not retaliating for an Israeli attack (I am not including assassinations here) and it is highly unlikely that it would want to set a new precedent for its enemies. We just have to wait and see when and how it will do so, because no matter how committed we are as observers we are not privy to Hizbullah’s military strategy. ."
