So basically, this is an extension of the US-Arab-Iranian conflict. In that case the Lebanese people are right not to trust either side, the (US+the Gulf countries) and (Iran+Syria). The past history does not encourage any trust in either side. The US has always considered Syria as a stabilyzing factor in Lebanon, and the Lebanese people have paid dearly for this policy since 1975 that lead in 1990 to a Moslem dominance over the Christians. It is time for the Lebanese to open their eyes very wide and stop playing the puppet anymore.
Well you are right that both sides shouldnt trust foreign powers. But March 14 is forced into requiring outside help because of hezbollah and the rest of the pro-syrians. They are getting help from outside forces and if march 14 doesnt do the same the pro-syrians will become more powerful/influential and they will win.
To be honest if i had a choice between having american influence in my country or iranian/syrian influence i would choose american in a heartbeat, isnt much of a decision to make really.
