TOE TO TOE WITH MOSCOW: Secretary of State Rex Tillerson travels to Russia this week on what will the biggest test yet of his diplomatic skills. Before Tillerson gets to Moscow on Wednesday, he stops in Lucca, Italy, for a two-day meeting of G-7 foreign ministers to consult  with U.S. allies about what comes next after last week’s U.S. cruise missile strike against Syria.

It’s unclear if Tillerson will get a face-to-face meeting with Russian President Vladimir Putin, who Tillerson knows from his days heading Exxon Mobil. But the secretary told the Sunday shows he will take a hard line, holding Moscow to account for its failure to deliver its promise to ensure Syrian President Bashar Assad gave up all his chemical weapons. “Russia gave certain assurances under the chemical weapons agreement in 2013 and in accordance with the U.N. Security Council resolutions that they would be the guarantor of the destruction of Syria’s chemical weapons stockpiles,” Tillerson told CBS. “Russia has failed in that commitment, and the result of their failure has led to the killing of more children and innocents.”
