The last time Ukraine signed a peace accord with Russia, 10 years ago, it brought only sporadic violence, mounting distrust, and eventually full-scale war. Here’s what we can learn from that history.

Russia rejected the United States-brokered ceasefire agreement for the war in Ukraine. Yuri Ushakov, a high-level aide to Russian President Vladimir Putin, dismissed the bid as a move to help Ukraine regroup while it’s on the back foot.

President Vladimir Putin of Russia did not outright reject U.S. President Trump’s ceasefire plan for Ukraine but is not ready to sign it.
