Why did east-central Europe find a non-violent freedom path in 1989-91, while the Arab world failed to do so after 2011?
A hundred years after the genocide of Armenians in the Ottoman empire, widening acceptance of the crime is shadowed by Ankara's continual evasion.
The massacre in Paris spreads fear and reinforces the retreat from free expression in Europe. It also sharpens an unavoidable choice over legal and political order.
Turkey is notably reluctant to join a military campaign against ISIS. In fact, Ankara's ambiguity towards the radical Islamist group has deep political as well as historical roots.
Azerbaijan’s strategy over the disputed, Armenian-held territory of Karabakh is also aimed at eliminating domestic opposition. But the country's rising troubles make this a self-defeating strategy.
The failure of the international community over events in the CAR reflects a wider retreat from its promises over human rights, says Vicken Cheterian.
The takeover by anti-Damascus rebels of an Armenian village in northern Syria, near the border with Turkey, has triggered a propaganda war which focuses on the position of Syria's Armenians. This highlights core aspects of Armenians' experience since the 1915 genocide, says Vicken Cheterian.
The civil war in Syria has put great strains on the country's Kurdish population. The Syrian Kurds' most powerful politician, Saleh Muslim Mohammad, talks to Vicken Cheterian about their position and future.
The revelation that modern Turkey continues secretly to classify its citizens according to religious criteria reflects the weight of the Ottoman past. It also has implications for those in the middle east seeking a state based on equality before law, says Vicken Cheterian.
The hopes of Syria's opposition for external support are turning into bitter suspicion of the west's real motives in refusing to intervene in the war, says Vicken Cheterian.
Much leftist analysis of Syrian events is trapped by a dogmatic outlook that combines a warped view of geopolitics with inattention to local realities, says Vicken Cheterian.
A new generation's encounter with the Armenian genocide of 1915 is producing fresh understandings of Turkey's - and the middle east's - modern history, finds Vicken Cheterian.
