HA will not retaliate for the simple reason that they will be on the losing side. Not that the LF are stronger, they’re not. It’s only because HA currently holds most of the power. If they decide to retaliate, they will lose men, they will further lose support, they will spend money and get men killed, and they will have to allocate ressources in areas that will weaken them in the south. Bottom line, It will weaken them.
It is not about who is stronger. The christians when the war started had nothing. The Army split and alot of its resources went to the LF. Then some countries from Europe and even Iraq started supporting the LF with weapons etc. You are fighting on land in Lebanon which is not yours aslan and to get to Me3rab you have to go through the christian hinterland. The LF are not these business men who are sunnis in Beirut who only care about a couple of shares in Solidere.
