An uneasy peace is holding in Libya, but progress towards a more enduring civil society is halting.  Libyan journalist Mustafa Fetouri says the biggest stumbling block is the presence of 25,000 or more armed foreign fighters in the country.  Turkey says, its forces -- mostly Syrian mercenaries -- were invited in by the Libyan government and so they -- alone-- should be allowed to stay. None of the other troop suppliers -- like Russia, Egypt and the UAE, are buying that.
