A ceasefire in Russia’s 3-year-old war in Ukraine hinges on Moscow accepting the U.S. proposal of a 30-day pause in fighting as a confidence-building measure for both sides to hammer out a longer-term peace plan.

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.

The barrage comes less than 24 hours after Russian President Vladimir Putin discussed details of the U.S. proposal for a 30-day ceasefire with a U.S. envoy.

Negotiators working to end the Russia-Ukraine war have already discussed “dividing up certain assets,” US President Donald Trump said Sunday as he announced he planned to speak to Russian President Vladimir Putin on Tuesday.

Zaporizhzhia nuclear power plant can produce enough energy for around four million homes and Donald Trump has suggested it could be discussed in peace talks.
