re: What the heck is the benefit of letting finland and sweden join NATO, more tit suckers

Sweden helps ensure that Russia cannot move subs out of the Baltic Sea undetected.

Finland allows NATO to stage troops and weapons close enough to the Cola Peninsula to, in the event of a first strike or pre-imptive strike by NATO against Russia, they could sever communications and take out nuclear launch sites in the Cola Peninsula before Russia can give the orders to retaliate. Basically, Finland joining largely neuters Russia’s threat of “mutually assured destruction” reciprocity.
