Ahead of today’s Trump-Putin summit in Alaska, Russian Foreign Minister Sergei Lavrov rolled up to the conference wearing a sweatshirt plastered with the letters “C-C-C-P.” That’s “U-S-S-R,” written in the Cyrillic alphabet. It was Lavrov’s cheeky way of reminding people that Ukraine was once a Soviet state. Coincidentally last week, two other former Soviet states in longstanding conflict just signed a peace declaration: Armenia and Azerbaijan. As Dorian Jones reports for our partners at Deutsche Welle, that agreement has big implications for Russia and for Turkey.
