Two months after a smiling Donald Trump and Vladimir Putin shook hands at a military base in Alaska in what looked like the start of a U.S.-Russia rapprochement, a top Russian diplomat has raised doubts that the ¡°spirit of Alaska¡± is still alive.

For Russia, the Anchorage summit on Aug. 15 had two goals: to persuade the U.S. president to lean on Ukraine and Europe to agree to a peace settlement favorable to Moscow, and to encourage a rapprochement in U.S.-Russia ties.

Russian Deputy Foreign Minister Sergei Ryabkov said this week there had been scant progress on either front and ¡°powerful momentum¡± had been lost. Moscow had signaled it was ready to rebuild ties but Washington had not reciprocated, he said.
