After Biden's swing through Europe, a six-month clock ticks for progress with Putin

President Joe Biden returned from a swing through Europe voicing optimism while starting a six-month clock during which the two countries will start nuclear security talks and the United States will determine whether the Kremlin has cracked down on cyberattacks from its soil.

“We’ll find out within the next six months to a year, whether or not there is actually a strategic dialogue that matters with Russia,” Biden told reporters during a news conference on the final day of his weeklong visit with European allies and partners. He met with Russian President Vladimir Putin on his final day, a meeting that began with Russian security scuffling the press pool and ended with the two leaders taking questions in separate press conferences.
