It could happen:

Lebanon is expected to be elected a non-permanent member of the UN Security Council for a period of two years at the end of next month, in the 64th session of the UN General Assembly.

With the backing of 21 Arab nations, Lebanon’s election is almost certain.

Under the Security Council rules, discussions concerning a country that is a member of the Council will require the said country to excuse itself from the session. Based on the UNSC track records over the past 5 years, Lebanon is more likely to spend more time at the water cooler than on the horseshoe table.
