We saw this coming. Everyone, from Condi to the French, to the Lebanese government have said that they aren’t going to disarm Hezbollah. So, when Israel tries to make sure Hezbollah doesn’t get any new weapons, they are accused of violating the cease-fire:

Hezbollah fighters battled Israeli commandos who landed near the militants’ stronghold deep inside Lebanon early Saturday, killing one soldier, in the first apparent large-scale violation of the U.N.-brokered cease-fire between the sides.
Hezbollah said its guerrillas foiled the raid after a gunbattle, and the Israeli army said one soldier was killed and two were wounded, one seriously.

The Israeli army said the special forces operation aimed “to prevent and interfere with terror activity against Israel, especially the smuggling of arms from
Iran and Syria to Hezbollah.” It said the commando team completed its mission.
The army said such operations would be carried out until “an effective monitoring unit” of Lebanese or multinational troops was in place.
“If the Syrians and Iran continue to arm Hezbollah in violation of the (U.N. cease-fire) resolution, Israel is entitled to act to defend the principle of the arms embargo,” Israeli foreign ministry spokesman Mark Regev said.
[…]
Israeli troops have killed several guerrillas who Israel said threatened its troops in south Lebanon since the cease-fire, and warplanes have flown over the country. But the cease-fire allows military action in self-defense, and the commando raid was by far the most serious incident since Monday.

In letters to Lebanese and Israeli leaders, U.N. Secretary-General
Kofi Annan has warned the two countries against occupying additional territory and told them to refrain from responding to any attacks “except where clearly required in immediate self-defense.”
Annan also told Israel and Lebanon that once the cessation of hostilities took effect there must be no firing from the ground, sea or air into the other side’s territory or at its forces.

I thought they retained the right to defend themselves? Isn’t that the right all nations have? No matter what they do now, it will be considered a violation.
