Just because the US changing its mind about Russia changes NATO's dynamic as a whole does not mean that the Baltic states are immediately in danger. Poland and Finland are both nearby NATO countries that have experienced Russia's thumb directly with their own military industrial base or are developing one that would absolutely step in if need be.

Reminder that Finland is really close to St. Petersburg, the 2nd largest city in Russia with some pretty big cultural and military importance. Putin's done some fantastically stupid stuff in regard to the 2022 Ukraine war, namely resuming it, but he's probably not that dumb.
