Maybe not with troops so long as they are tied down in syria but if it is with troops russia will probably deny it like they did when they invaded Ukraine but they probably will start sending all this BS about the Finish Government through RT and cyber attacks and try to get people to start wanting to be russian, or by making it look like it.
Russia has made some aggressive moves lately and it sees likely that they will start to act on them. If they attack Finland it is likely to be the start of another world war, but they might actually do it this time. They have lots of weapons and a big army.
Yes, Russia will attack Finland, but it is unclear how they will go about it. For instance, Russia is using cyber attacks against the US. They may do the same to Finland, or they may send in troops. The world is changing quickly and the way a country attacks another is evolving just as fast.
Russia will not attack Finland because the attack would spur many nations turning on Russia . Many countries are unsettled with Russia's political tactics and would be willing to defend Finland. This would put Russia in a very bad defensive position, and probably causing them to lose global power and reputation, weakening the nation.
Russia will not attack Finland because such a move would be totally unreasonable. We live in the 21st century and open conflict between two European countries is impossible because it would lead to much bigger world conflict. Russian have good relationship with Finland, both economic and cultural, and questions about the legality of Finland 1917 independence is outdated.
