Finland's accession to NATO highlights that Russia's full-scale invasion of Ukraine has been a "strategic failure," according to US Ambassador to Poland Mark Brzezinski.
"What's changed in the last week is that NATO has expanded in a way that just emphasizes the strategic failure of (Russian President Vladimir) Putin's decision to invade Ukraine," he said in an interview with CNN's Michael Smerconish on Saturday.
"What we are seeing is an amplified total failure on the part of Putin regarding his decision to invade poor, weaker Ukraine. And there is no way, no way, Putin's war in Ukraine has improved the lives and the futures of the Russian people," he said.
His remarks echo those of US Secretary of State Antony Blinken, who visited Finland on Friday. Blinken also called Russia’s war a "strategic failure," saying it has diminished the country's influence and interests "for years to come."
Finland officially became the 31st NATO member in early April. The Russian invasion drove traditionally non-aligned Finland and Sweden to abandon their neutrality and seek to join the alliance.
When asked if any possible peace negotiations are ongoing, Brzezinski said:
"Every minute of every day, the American government stands ready to advance the path of diplomacy. But instead, Russia is advancing the path of aggression. What I thought was particularly important that Sec. Blinken emphasized yesterday is that we're going to make sure not only that the Ukrainian people win this war and survive, but that they thrive."
"We're committed to a path of making sure a lasting peace includes a complete reconstruction of Ukraine and a drawing into it — as it wants — into the Western institutional orbit. And that's the opportunity here: to have a renaissance, emerge out of this crime of a war in central and eastern Europe," he said.
Brzezinski also said he believes the majority of US lawmakers remain committed to providing assistance to and showing solidarity with Ukraine. He noted that he's hosted over 150 members of Congress from both parties, including former House of Representatives Speaker Nancy Pelosi and current Speaker Kevin McCarthy.
