Predictably, the headline bears no relation to the truth of the article. Putin didn’t agree to anything, and Trump himself is quoted as a saying Putin’s response is “promising” but not “complete”.
This what Putin agreed to according to his statement: “We agree with the proposals for the ceasefire, but our position is based on the assumption that the ceasefire would lead to a longterm peace, something that would remove the initial reasons for the crisis.”
All the posturing is for negotiating.
