I STANBUL—President Trump’s ultimatum for Russian President Vladimir Putin is showing no signs of bringing Russia and Ukraine any closer to peace. The third round of direct talks between Ukrainian and Russian officials, held Wednesday in Istanbul, yielded few results. The two sides met for less than an hour.

Ukraine, Russia hold third round of peace talks in Istanbul ・Ukrainian drones reportedly target key logistics hub in southwestern Russia ・Russia suffered 80,000 casualties during Kursk incursion, Ukraine's military chief says ・'He sees Trump as emotional and susceptible to influence' — Putin not worried about 50-day

Putin’s refusal to compromise on Ukraine, say analysts, is a colossal error costing Russia regional influence, lucrative energy markets and its place in the world.
