(CNN) -- A most awkward and revealing situation has emerged in the heart of Europe, forcing European governments to choose between their principles and their fears, and drawing an uncomfortable gap between Europe's words and its actions. Last July, a bus carrying tourists about to start their vacation suddenly exploded outside the airport in the Bulgarian city of Burgas. The bombing killed five Israelis -- including a pregnant woman -- and a Bulgarian driver. This week, Bulgaria's foreign minister blamed  Hezbollah, saying an investigation showed the attack was carried out by two members of the Iran-linked Lebanese organization. Hezbollah denied the accusation. But Bulgaria says it discovered strong links, with "data showing the financing and connection between Hezbollah and the two suspects."

Ghitis: In letting group claim legitimacy, EU passively abetting a terrorist organization
