As His Fortunes Fell in Ukraine, a President Clung to Illusions

Mr. Yanukovych, for his part, had begun discussions with the European mediators. According to Mr. Sikorski, the Polish foreign minister, the president was digging in his heels, telling the French, German and Polish diplomats that he was not to blame for the crisis and refusing even to consider setting a date for an early election.

Mr. Sikorski said he told Mr. Yanukovych that the only way to sell a deal to the opposition was to specify when a new presidential election would be held. “You need to declare on what date you’ll resign,” he said he told the president.

Mr. Yanukovych “went white,” Mr. Sikorski said. But the deadlock lifted after the Ukrainian leader received a phone call shortly afterward from President Vladimir V. Putin of Russia. “He came back, he was agreeing to limit his time in office,” Mr. Sikorski said. “That made everything possible.”

He was prepared to stay in his house until he noticed all his guards left….

By late Friday afternoon, Mr. Yanukovych’s time had run out. Between the signing ceremony for the peace deal, held at the vast, colonnaded building that houses Ukraine’s presidential administration, and his break for Olympic cheerleading, the president’s prospects had taken a dramatic turn for the worse: Hundreds of riot police officers guarding the presidential compound and nearby government buildings had vanished.

“It was astonishing,” said Mr. Sikorski, who, while leaving the presidential building, watched in dismay as the police officers jumped into buses and drove off. “That was not part of the deal. Astonishing.”
