YEREVAN, Armenia — Will Turkey's current turmoil between Prime Minister Recep Tayyip Erdogan and the country's powerful army complicate and delay the country's boldest initiatives in years — the moves to address decades-old tensions with both Armenians and Kurds?

Restructuring the role of Turkey's army is vital, but if Turkey cannot follow through with the Armenian and Kurdish openings, then its own domestic situation, its relations with the two peoples and tensions in the Caucasus will undoubtedly worsen.

Of the several flash points in the region, including that between Georgia and Russia over South Ossetia and Abkhazia, the tension between Armenians and Azerbaijan over Nagorno-Karabakh is among the most challenging.
