Lebanon has a population of about 3.6MM people. That percentage of the population can't be totally manufactured. I am sure they had help but there is a true backing for Hezbollah and Syria among the Muslim population in Lebanon.
but 12 seats in Parliament says they have some but not majority support, if they are supported by one third of the Shia Muslims, that means two thirds of the Shia Muslim in Lebanon do not support Hezbollah and what portion of the Lebanese population, without the Syrians (who are mainly Sunni Muslim I believe) is Shia?
I suspect neither the majority of the Lebanese nor even the Syrians want an Islamist state which is Hezbollah's main goal for Lebanon (I'm sure they got their eyes on Syria next)
