American, European, and Arab officials I spoke to told me that the Siniora government and its allies had allowed some aid to end up in the hands of emerging Sunni radical groups in northern Lebanon, the Bekaa Valley, and around Palestinian refugee camps in the south. These groups, though small, are seen as a buffer to Hezbollah; at the same time, their ideological ties are with Al Qaeda.

During a conversation with me, the former Saudi diplomat accused Nasrallah of attempting "to hijack the state," but he also objected to the Lebanese and Saudi sponsorship of Sunni jihadists in Lebanon. "Salafis are sick and hateful, and I’m very much against the idea of flirting with them," he said. "They hate the Shiites, but they hate Americans more. If you try to outsmart them, they will outsmart us. It will be ugly."

Alastair Crooke, who spent nearly thirty years in MI6, the British intelligence service, and now works for Conflicts Forum, a think tank in Beirut, told me, "The Lebanese government is opening space for these people to come in. It could be very dangerous." Crooke said that one Sunni extremist group, Fatah al-Islam, had splintered from its pro-Syrian parent group, Fatah al-Intifada, in the Nahr al-Bared refugee camp, in northern Lebanon. Its membership at the time was less than two hundred. "I was told that within twenty-four hours they were being offered weapons and money by people presenting themselves as representatives of the Lebanese government's interests—presumably to take on Hezbollah," Crooke said.
