Just showing where her true loyalties lie — NOT with western civilization.
My opinion.
The Finns have been on the fence since the Cold War began. Part of it was Finland's alliance with the Nazis and war with the Soviets during WWII. Part of it is probably the hope that they can emerge unscathed while the West wards off Russia. Now that the Russians appear to be peeling off anyone not aligned with the West via a defense treaty, they are starting make noises about joining NATO. My guess is that they'll join minutes after Russia crosses the Finnish border.
