European Union governments added Hezbollah's military wing to their list of terrorist organizations on Monday, an abrupt policy reversal that could result in visa bans and the freezing of assets belonging to individuals and groups linked to Hezbollah, a Lebanese Shiite militant group. The point, EU ministers said, was to send Hezbollah leaders a warning and to make it harder for them to make trouble abroad.

The blacklisting came in response to an escalation of Hezbollah's alleged activities in Europe, including a 2012 attack blamed on the organization that killed five Israelis and a Bulgarian at a Black Sea resort in Bulgaria. A Hezbollah operative was also convicted of planning a similar attack in Cyprus. Support for the sanctions grew recently as Hezbollah began sending fighters to help President Bashar al-Assad's forces battle rebels in neighboring Syria.

Lebanese caretaker Foreign Minister Adnan Mansour said the decision was "hasty" and could destabilize Lebanese politics, but many Middle East experts see the EU's decision as an overdue warning to Hezbollah. Walter Russell Mead says at The American Interest that it has long been clear that Hezbollah's armed wing deserved to be added to terror lists, but the group's support for "Butcher Assad" and the textbook terrorism case in Bulgaria made it pointless to try denying the truth any longer.

Quietly scolding Hezbollah certainly has not worked, as its recent push in Syria proved. "This could be a game-changer," says Domhnall O'Sullivan at EU Observer, but there's also a chance it could backfire.

The accompanying sanctions could be a nightmare to implement, since untangling people in Hezbollah's secretive military wing from its political and social operations will be difficult. The non-military side of Hezbollah has elected representatives in Lebanon's government, and funds extensive social welfare programs, including hospitals and schools.

The Jerusalem Post says in an editorial that only putting part of Hezbollah on the terrorism list won't be enough to make a difference. "Listing only its 'military wing' is a start, but there is no real difference between the wings," the Israeli newspaper says. "Nevertheless this is a minimum first step in confronting an organization that has for too long terrorized not only the region, but EU member states such as Bulgaria as well."
