Hezbollah vs. Israel: "... the fall of three spy networks should not be taken lightly ...someone was clearly careless in running the operations .."

Yossi Melman, in Haaretz, here

"... Therefore, Israelis can only rely on what is published in the Lebanese media or Arab news outlets, which base their reports on information obtained from the Lebanese security services. Hezbollah is always a partner, often a senior one, to such investigations. ...

As a relatively small organization, the Mossad strives to obtain high-quality sources in the target country's top echelons. Immediately after the Iranian nuclear program and efforts to thwart it (so far unsuccessful) became the number one target for intelligence-gathering, the fight against terror organizations - first and foremost Hezbollah - has been the main priority. ...

If the Lebanese media reports are correct, the fall of three spy networks should not be taken lightly, especially if the discovery of the first led to the fall of the others. If this is what happened, then someone was clearly careless in running the operations, the basic rule of which is complete compartmentalization between networks and between one agent and another. In such cases, handlers tend to lower their profile and reduce future operations until the storm blows over. 

It also seems Hezbollah has become more alert in the wake of suspicions that the organization was infiltrated. However, in the end, the uncovering of an espionage network or the fall of an agent, with all the regret these entail, are part of the way the game is played. These are the facts of life in clandestine activity."
