Just a note, while Baltic banks are well integrated into the EU (especially after the Danske bank scandal and others before it made integration with Russia politically toxic) the energy grid of the region is still very tied into Russia which is of a critical concern right now (see EU energy prices and issues with the harmonization across the union).

I will also have a very negative posture on the EU military spending/capability unfortunately after working for a Baltic government and being familiar at a high level at capabilities in the region and somewhat familiar of Germany/France. In the EU today now that Britain has left, France is the only real military power who has 1) the forces to deploy and 2) the will to do so. German forces are in a terrible state of disrepair and the new government does not seem like one to invest further (Ulrike Franke has a great writeup and is worth a twitter follow) and even the old gov is under fire for blocking military aid as they have supported nonlethal NATO equipping only to Ukraine, I would guess partially because they are addicted to Russian gas but there are some rumors that Merkel will join some Russia affiliated boards (gotta love a little government graft). Poland I am less clear about but I have never heard anything about them having a really solid air force and anti-air capabilities which is one of the most critical things Ukraine needs (at this point Ukrainian ground forces are actually pretty good and are well versed in how to fight; what they need is to be able to ward off incursions by sea and air).
