How long is too long?

As the UN calls for restraint and additional UN Peacekeeping forces in Lebanon, one must has the question, "how long is too long?" The UN has had ineffective peacekeeping forces in the area since 1978 directly on the Israel/Lebanon border During the time that the UN has been keeping the peace, American forces have been attacked, Hezbollah developed and ran rampant, and of course,more recently, under the very noses of these useless forces, Hezbollah kidnapped two Israeli soldiers inside Israel.

The question should be, "How long does the US have to foot the bill for this corrupt and totally inefficient body?"
