> And how is these countries joining NATO benefiting the existing NATO members? Finland has one of the bigger armies in Europe (way bigger then many of the existing european NATO members). At least for the baltic NATO members Finland being a member is a huge boon basically blocking Russian fleet into the bay where Saint Petersburg is as the Gulf of Finland is rather narrow (you can literally see from Helsinki to Tallin if you go top of a tall building) completing the encirclement of Russia on its western border. Sweden also helps with controlling the Baltic sea due to Gotland.
