Hezbollah is a terrorist organization. 

yet, it is not recognized by the EU institutions as one.
It has conducted terrible acts of terrorism on Western targets in recent decades, Given the unrelenting and lethal activities of Hezbollah, we urge the EU to designate Hezbollah as a terrorist organization. 
EU member countries have suffered the tragic consequences of Hezbollah violence, supported by Iran, Hezbollah's founder and principal supporter.

Therefore we call upon the EU institutions to add Hezbollah to the their terrorist group list.
