In an interview with Yle and other Nordic news outlets, Ukrainian President Volodymyr Zelensky said his nation's war against Russia cannot end the same way as World War II did for Finland.
Finland not only ceded territory to Russia, Zelensky noted, but also lost many lives.
"I believe that such an opportunity cannot be given," he said.
He further added that it was both "insulting and unfair" that other countries did not help Finland in its efforts to repel Russia, a likely reference to the Winter War of 1939-1940.
During the course of the interview, Zelensky thanked the Nordic nations for the support they have given Ukraine since Russia launched its invasion in February last year.
"The Nordic countries, unlike some other partners, have not broken their promises," he said.
Zelensky wants Finnish help with air defence
As government formation talks advance in Finland, Zelensky said it was too early to tell if Finnish policy towards Ukraine would change with the incoming coalition.
"I hope that cooperation will also be good with the new Finnish government, because Finnish society supports Ukraine," he said.
In particular, Ukraine is looking to Finland for help with air defence — for example by Finland sending old Hornet jets to Ukraine after they are decommissioned.
Outgoing Finnish Prime Minister Sanna Marin (SDP) raised the subject of potentially loaning the fighter jets during a visit to Kyiv in the spring, but later clarified that she said Finland could discuss the possibility.
The possibility of donating F-16 fighters to Ukraine has been discussed by other countries.
Handing over either of the fighter aircraft models to Ukraine would require the permission of the United States, which is the manufacturing country, but so far the US has not given the green light.
Zelensky: Counter-attack needs Western weapons
Zelensky confirmed to Yle that Ukraine is planning a counter-attack, noting that he believes it will be successful in repelling Russia's forces and also returning the Crimean peninsula to Ukrainian control.
However, he added that Ukraine's success depends heavily on the West continuing to supply weapons.
"We want to save as many lives as possible, so the number of weapons matters," he said.
He also noted that Russian troops are losing motivation by the day.
"They are afraid of us and also of the consequences if they retreat," the Ukrainian president said.
Although Zelensky did not want to disclose any details or timetable for the counter-attack, it is generally believed to be planned for late spring or early summer.
Despite his hopes for success, he also warned that the war could continue for years or even decades.
"It is cheaper for other countries to support Ukraine now than increase the risks of a third world war," Zelensky said.
Zelensky: I am not a good father
During the interview, Zelensky also spoke about his own state of mind and stamina — noting that he cannot just take a holiday from the war.
"I live through all the tragedies. I have no right to say that we are used to war," he said.
Zelensky and his wife Olena Zelenska have two children. He said that trying to balance running a country at war with fatherhood is an impossible task.
"People say I'm not a bad president, but I'm certainly not a good father at the moment. My children are being raised by my wife and the war," he said.
However, despite the considerable toll the war is taking on Zelensky, his family as well as his country, the Ukrainian president remains upbeat.
"The first time we liberated a region was like a taste of new life," Zelensky said.
