Stubb said the intelligence response to Russia was too "acute".

On September 21, Finnish President Alexander Stubb announced an overly acute reaction of some intelligence services to alleged possible threats from Russia.

"We don't see any evidence of that. We believe that we need to remain vigilant and on our guard. But, you know, we have the longest border with Russia among all the NATO countries — this is half of the entire border of the alliance with the Russian Federation. Our intelligence shows that there is activity, but there is no immediate military threat at the moment," Stubb said in an interview with Politico on the sidelines of the UN General Assembly in New York.

He also noted that some special services actually create the impression of an allegedly imminent Russian strike, although there is no evidence of such fears.
