This is such a mess, how the heck is Israel ever going to be safe from attack if they leave these terrorists fully armed? Annan is makes it clear they aren’t going to be disarmed:

“The troops are not going there to disarm Hezbollah. Let’s be clear about that,” he said.
Regev reiterated Israel would not lift its air and sea embargo of Lebanon until peacekeepers take positions along the Syrian border to block arms shipments to Hezbollah from its two main supporters, Iran and Syria.
But Annan said peacekeepers would deploy on the Syrian border only at Lebanon’s request, which Beirut has yet to make. Such a move would aggravate tensions with Syria, which views the deployment of international troops along the border as a hostile act.
“The resolution does not require the deployment of U.N. troops to the border,” Annan said at a news conference after a three-hour meeting with the 25 EU ministers Friday.
