Russian President Vladimir Putin said in an interview with Kremlin-controlled media Russia-1 about his intention to boost forces along the country’s border with Finland in response to Finland’s accession to NATO.
Putin gave the interview with Russia’s RIA state news agency and Rossiya-1 state television before the presidential elections in Russia, which will take place on 15-17 March and certainly secure him another six years in power.
Criticizing Finland and Sweden’s move to join the military alliance, Putin stated in an interview with Russia’s RIA state news agency and Rossiya-1 state television, “This is an absolutely meaningless step (for Finland and Sweden) from the point of view of ensuring their own national interests.”
According to Reuters, he also said, “We didn’t have troops there (at the Finnish border), now they will be there. There were no systems of destruction there, now they will appear.”
