Yes, I dont know enough.
They are exploiting the nationalist cause, they are a sectarian militia. They fight for their people and they fight to be the dominant force in Lebanon. These are not mutually exclusive categories.
it is. I mena they have had some real success, but it does not change their character. Without them Lebanon would still be occupied though.
It's unlikely anyone will fight your battles for you. You have 350 million Arabs that should be the first to fight. They clearly are reluctant to do so. Iran and countries further out you cant really rely on them either.
I sympathise with you and your cause, but I have too much to lose if my country 5,000 km away gets flattened trying to help. countries exist to protect their people.
But I have no doubt that at some stage you will be victorious.
