British spy chief predicts Russian forces will soon "run out of steam" in Ukraine

Head of the British intelligence service MI6 Richard Moore said Thursday that Russian President Vladimir Putin had thus far suffered a "strategic defeat" in Ukraine, failing to achieve any of what Moore described as three key objectives — removing Ukrainian president Volodymyr Zelenskyy from power, taking control of the country's capital, Kyiv, and sowing disunity within NATO.

"On all of those," he said, "I think they count as epic fails."

Moore, who took part in a question-and-answer session at the annual Aspen Security Forum in Aspen, Colorado, predicted that Russian forces would be forced to regroup within "the next few weeks," offering Ukraine a crucial window within which to make battlefield reversals.
