Currently, the war in Ukraine is ongoing which become a big concern for other EU members. Many countries like Poland, and Germany have increased their defense budget. After invading Ukraine Putin warns other non-NATO members(Sweeden and Finland) along with its border not to join NATO or they will face destructive consequences. After that support for joining NATO in that two respective countries increased above 50%.
Russia or we can say the former soviet union took major losses in the previous Finland invasion. Both nations have advanced military technology compared to Ukraine. Some NATO countries said Russia could attack Finland before it will be able to join NATO. So it could be Putin's last decision to invade any country if he really tries to invade Sweden and Finland.
Finland and Sweden could soon join NATO, prompted by Russian war in Ukraine
In a recently published video, I have seen the Russian military movement close to the Finis border.
