Russian President Vladimir Putin must pay an unacceptable cost if he decides to invade Sweden or Finland following their formal request to join NATO, an expert has claimed.

Putin sees NATO's eastward expansion as a threat to Russia ’s borders and is displeased with the increased western alliance with Ukraine — one of the motives behind the devastating invasion.
