During a visit to Russia on 21 August 2012 Jamil said that President Bashar Assad's resignation might be considered if the opposition agreed to negotiate a peaceful settlement to the Syrian revolution.

As this illegitimate procedure, as described by those affected, was widened to cover more party organizations all over Syria, Jamil and his comrades formed the National Committee for the Unity of the Syrian Communists, which published the Qassioun (also Kassioun) newspaper.

As the Syrian popular movement turned armed and violent, the PWP continued with its humanitarian aids and mediation efforts in some conflict zones.

[10] Jamil "thanked" Russia for vetoing a UN Security Council Resolution in December 2011 that would have condemned the Syrian government.

[14][15] Just before the official announcement of the election results, Jamil denounced them as "forged and manipulated", and said they would not be a starting point for political reform in the country.

Jamil was removed from office on 29 October 2013, for leaving the country without prior permission and reportedly meeting with U.S. envoy for Syria Robert Stephen Ford to discuss proposed Geneva peace talks.
