No reason to trust Russian rhetoric, says UN ambassador Bob Rae

Canada's ambassador to the UN says there's no reason to trust Russia when it comes to ending its invasion of Ukraine and that the international community must get to a point where the costs of the ongoing war are clear to President Vladimir Putin.

The way to do that is to convince Russia that the international community is firm in its commitment to supplying Ukraine with substantial military, financial, humanitarian and moral support, Bob Rae said in an interview on CBC's The House that aired Saturday.

"So, it's a brutal business, but we have to convince the Russians that there is a price for their conduct and they are not going to sweep over Ukraine the way they thought they could," Rae told guest host Tom Parry.

Russia recently claimed that it had succeeded in the initial phase of what it calls its "special military operation" in Ukraine and would now work to "liberate" the Donbas region. Intense fighting continues in the country, especially around the besieged southern port city of Mariupol.

"Based on the experience that we've had with Russia in the last four months, I wouldn't believe a word that they said," Rae said. "I think we have to base it on what they actually do."

The lack of Russian credibility is part of what prompted Rae's team to mock a letter sent by the Russian delegation to the UN, which went viral of social media and which Rae said he endorsed.

The UN ambassador, whose previous life in politics saw him serve as NDP premier of Ontario and interim leader of the federal Liberals, noted Russia's claims early in the year that troops massed at Ukraine's border were not an invasion force.

"They were lying to us the whole time. So, why would we think that they're not lying to us now?" he said.

"We've got to get to a point where a ceasefire will be meaningful and will produce the conditions for a successful resolution to the conflict," Rae said. "It's a conflict that obviously depends a lot on what happens on the battlefield."

In a separate interview on The House, Ukrainian MP Inna Sovsun said the fighting around the capital city of Kyiv had stabilized in the past week or so but explosions could still be heard as Ukrainian and Russian forces fought over nearby cities and suburbs.

Sovsun said since the start of the war the key to protecting Ukraine has been stopping Russian airstrikes.

"You can never feel safe because of the airstrikes. Whether you are in western Ukraine, in Kyiv or anywhere else, you are always under the danger that a bomb will fall on your head," she said.

"We are not asking the world to get involved directly … but at least give us the weapons that we need in order to cover the sky in order to establish a no-fly zone ourselves."

Canada and other NATO countries have said they are continuing to work to deliver weapons to Ukraine, but have maintained the alliance's military forces will not enforce a no-fly zone, as it would risk direct, escalatory conflict with Russia.
