An attempt of the pro-Saudi opposition to bargin a cease-fire in exchange for its participation in the talks seems to have failed. As did Turkey's attempt to exclude from the negotiation process the Syrian Kurds not linked to the Barzani family who completely sold themselves to the Turks and got bogged down up to their ears in smuggling of oil from Iraq and Syria.
The tactics of the Kingdom of Saudi Arabia and the "opposition" to negotiate a peaceful settlement in Syria in the best traditions of the Ukrainian negotiators did not bring any results. The Ukrainian negotiating traditions, let me remind you, are - to pester to no end and under the guise of negotiations to drag on in order to have time to modernize army, not to comply with the Armistice Agreement, to hide behind civilians, by deception and provocations to return to the demilitarized territories from which the army was previously pulled out.
