"As it was discussed here war in Baltic States are not advantageous for both sides and will lead to plenty of worse consequences. So its fair to say that likelihood of such invasion is not possible. However, as long as Russia continues its war in Ukraine, does not end occupation of Crimea and continues intervention in Syria the danger of Russian military aggression stays. As it was stated here Russia often does not need a logical or rational reason to start a war the decision can be based on fear, hate, power mongering and oversight. Thus the war can be caused by simple unforeseen incident like in Sarajevo 1914 when few shots brought whole Europe to war that was waiting for it for last few years. So there is no reason to competently override the danger of Russian invasion. As long as aggressive, suspicious and totalitarian regime is in power in Moscow that relies heavily on its military success the danger will stay and should be considered and prepared for."
