According to Lebanon Now Hezbollah has built a concensus that is very fragil and likely to fall apart if Hezbollah lead the country into war with Israel.
This poses potential problems for Sayyed Hassan Nasrallah, Hezbollah’s secretary general. His implicit contract with Iran is that his party be prepared to protect and advance Tehran’s interests in the Levant, to the extent that Hezbollah would retaliate against Israel if the Israelis were to bombard Iranian nuclear facilities. But for such a project to be effective, for Hezbollah to go to war with confidence that its countrymen are not working behind its back against its interests, the party would have to enjoy widespread Lebanese backing.
That may be so but I don’t believe it would stop Hezbollah from following Tehrans orders.
