US PRESIDENT JOE Biden said today he believes his Russian counterpart Vladimir Putin is a normally rational actor who badly misjudged his prospects of occupying Ukraine.

The president spoke out in a rare televised interview as his administration looks for what he has described as an “off-ramp” for Putin to deescalate his invasion of Ukraine before he resorts to weapons of mass destruction.

“I think he is a rational actor who has miscalculated significantly,” Biden told CNN after Moscow’s shelling of civilian targets across its neighbor marked an escalation in the seven-month conflict.

Biden warned last week that the world risks “Armageddon” in unusually direct remarks about the dangers from Putin’s thinly veiled threats to use nuclear weapons to assist Russia’s faltering attempt to take over swaths of Ukraine.

Putin’s state of mind has been the subject of much debate after the Russian president suffered a series of recent military set-backs in the invasion, which he launched in February.

In remarks released by CNN ahead of its broadcast of the interview today, Biden said that while he believed Putin himself was rational, he had underestimated the ferocity of Ukrainian defiance.

“I think… he thought he was going to be welcomed with open arms, that this was the home of Mother Russia in Kyiv, and that where he was going to be welcomed, and I think he just totally miscalculated,” Biden said.

Kyiv’s forces have in recent weeks been pushing back against Russian soldiers across the front lines in the south and in the east.

Ukrainian President Volodymyr Zelenskyy said Friday his troops had recaptured nearly 2,500 square kilometers in the counter-offensive that began late last month.

‘Further escalation’

But the Ukrainian defense ministry said yesterday that Russia had retaliated with a massive bombardment of its neighbor, hitting the Ukrainian capital Kyiv for the first time in months, as well as other cities across the country.

Biden spoke to CNN hours after meeting virtually with members of the Group of 7 industrialized nations, who heard from Zelenskyy on the need for intensified efforts to “create an air shield for Ukraine” amid the barrage of Russian cruise missile and drone attacks.

Zelenskyy told the G7 “millions of people would be grateful” for help fending off attacks from the sky, and he warned Russia “still has room for further escalation.”

Washington pledged that it would up shipments of air defenses to Ukraine, while Germany promised delivery “in the coming days” of the first Iris-T missile shield reportedly capable of protecting a city.

In the CNN interview, Biden’s first with the cable news channel since taking office, he criticized Putin’s aim to be “the leader of Russia that united all of Russian speakers.”

“I mean… I just think it’s irrational,” Biden said.

The president frequently takes questions from the media, but he has held few press conferences or one-to-one televised interviews.

He has been more visible recently as he takes to the road to talk up Democratic legislative achievements and slam “MAGA Republicans” – followers of former president Donald Trump’s “Make America Great Again” agenda – in the final weeks of the midterm election campaign.

He also sat with CBS in September, making headlines for declaring the Covid-19 pandemic over and confirming US commitment to defending Taiwan from a Chinese assault.
