US spy chiefs say Putin may escalate despite Ukraine setbacks

They estimated that 2,000 to 4,000 Russian troops had died and said Russia was feeling the effects of sanctions, but the situation could become much worse for Ukrainians, with food and water supplies in Kyiv possibly running out within two weeks.

"Our analysts assess that Putin is unlikely to be deterred by such setbacks and instead may escalate," Director of National Intelligence Avril Haines told the annual House of Representatives Intelligence Committee hearing on worldwide threats, where she testified with other intelligence agency directors.

Haines said Putin's announcement that he was elevating his nuclear forces' readiness was "extremely unusual" since the 1960s, but that intelligence analysts had not observed changes in Russia's nuclear posture beyond what was detected during previous international crises.

"We also have not observed force-wide nuclear posture changes that go beyond what we've seen in prior moments of heightened tensions," Haines said.

William Burns, director of the Central Intelligence Agency, echoed Haines' assessment that Russia is unlikely to back down.

"I think Putin is angry and frustrated right now. He's likely to double down and try to grind down the Ukrainian military with no regard for civilian casualties," Burns said.

Burns said he and CIA analysts do not see how Putin can accomplish his goal of taking Kyiv and replacing President Volodymyr Zelenskiy's government with a pro-Moscow or puppet leadership.

"I fail to see how he can produce that kind of an end game and where that leads, I think, is for an ugly next few weeks in which he doubles down ... with scant regard for civilian casualties," Burns told the committee.

'DESPERATE' IN KYIV

Given reports that Russia is cutting off basic supplies to Kyiv, home to 2.8 million people, Lieutenant General Scott Berrier, director of the Defense Intelligence Agency, said the situation in Ukraine's capital could worsen quickly.

"I don't have a specific number of days of supply that the population has. But with supplies being cut off, it will be somewhat desperate in, I would say, 10 days to two weeks," Berrier said.

Berrier said the United States did not have evidence that Russia had committed war crimes beyond what has appeared on social media. Berrier said that "the bombing of schools and facilities that are not associated with the Ukrainian military certainly would indicate that he is stepping up right to the line if he hasn't done so already."

Burns said China's leaders are "unsettled" by events surrounding the assault on Ukraine, despite refusing to condemn Russia or call the attack an invasion.

"They did not anticipate the significant difficulties the Russians were going to run into. I think they are unsettled by the reputational damage that can come by their close association with President Putin; second by the economic consequences at a moment when they are facing lower annual growth rates than they've experienced for more than three decades," Burns added.

"I think they're a little bit unsettled about the impact on the global economy. And third, I think they're a little bit unsettled by the way in which Vladimir Putin has driven Europeans and Americans much closer together," Burns said.

The United States has done "intensive intelligence-sharing" with Ukraine, Burns said.

Berrier said his "low confidence" assessment was that 2,000 to 4,000 Russian troops have been killed.

Russia calls its actions in Ukraine a "special operation" that it says is not designed to occupy territory but to destroy its southern neighbor's military capabilities and capture what it regards as dangerous nationalists.

At the hearing, Democratic and Republican committee members praised the work done by the U.S. intelligence community ahead of the Russian invasion.
