Over the last decade, Hezbollah has worked assiduously to obscure its terrorist pedigree and convince the world that it is interested only in politics, providing social welfare services, and defending Lebanon. But it is an illusion to speak of Hezbollah as a responsible political actor. Hezbollah remains a terrorist organization and a destabilizing force across the Middle East.

Since 2011, the group has murdered civilians in Bulgaria, seen its activities disrupted in Cyprus and Thailand, and worked to plot attacks elsewhere. It is helping to prop up the brutal regime of Bashar al-Assad in Syria; and it acts as a proxy for Iran’s Islamic Revolutionary Guards Corps in the region and beyond. In doing so, Hezbollah is putting the well-being of Lebanon and its people at risk.

Now that Bulgarian authorities have exposed Hezbollah’s global terrorist agenda, European governments must respond swiftly. They must disrupt its operational networks, stop flows of financial assistance to the group, crack down on Hezbollah-linked criminal enterprises and condemn the organization’s leaders for their continued pursuit of terrorism.
