After observing Finnish Army field exercises in North Karelia, Niinistö suggested that Finland can help Ukraine's war effort, telling reporters that it would back up the military equipment it is sending to Kyiv with the training required to operate it."Of course, training on these could be very appropriate," Niinistö said on Tuesday, Finnish media outlet YLE reported, "we know how to use them."Niinistö had observed his country's Kontio 22 exercises which started last week and finished on Friday, and involved the Army working with Finnish Air Force and Border Guard troops.In February, Niinistö compared the tensions before Russia's full-scale invasion of Ukraine to pre-Winter War Finland, when Soviet leader Joseph Stalin thought he could divide the Finnish population, but instead the population came together."Of course, the long land border with Russia means Finland is quite exposed, but Finnish confidence has probably also been boosted by the momentum produced by Ukrainian recovery of territory in recent months," she told Newsweek."
