I don't think Hizbullah was ever frightened as it is now. Israeli tanks and shells may have killed its fighters and leaders in the past, but it never dented its image as the upcoming STL indictment potentially will.
It might be hard to accept that the Iranian funded militia is digging its own grave by effectively suspending the Lebanese government. However, the indictment will definitely help shatter whatever Hizbullah's knee jerk reactions of recent months have not already blown to smithereens.
They can have fun weaving conspiracy theories all they want. But Hizbullah's standing is forever tarnished after the report comes out. What they prevented Israel from achieving they are doing unto themselves. First by rejecting the course of justice and alienating at least half of the Lebanese population. Second by having participated in the plot to destroy Lebanon through killing its prime minister, and by aiding and abetting in the murder of its intellectuals and policy makers.
I don't know about you, but I believe Hizbullah quitting the cabinet is a good development. A militia should not be allowed into government. Thugs who have foreign and extremist agendas should not be allowed to rule or partake in any democratic process. For, and people forget, Hizbullah is not a political party, and cannot participate in any democratic process because of its very nature as a militant theological entity that does not recognize the authority of the state or elected officials. They should have no right to run in elections or name anyone to head a government.
Good riddance, Hizbullah. And as for Aoun and Assad and their despicable puppets, may they enjoy being on the wrong side of history.
