Syria’s relentless campaign of intimidation and destabilization in Lebanon has taken the life of yet another prominent Lebanese democrat. The best answer to this tragedy is for the international community to intensify its commitment to a full and uncompromising investigation of the Hariri assassination and all subsequent political murders in Lebanon, an investigation that Damascus is transparently and ruthlessly trying to prevent.  The UN Security Council should immediately approve a fully empowered international tribunal to investigate these crimes. My colleagues in the U.S. Congress and I firmly support the democratically-elected Lebanese government and all democratic Lebanese.
