If you look at the Baltic Sea before and after the invasion of Ukraine, that was largely a neutral space (before) that has since turned into a NATO one -- excluding only the Russian exclave of Kaliningrad.
I would argue this makes any further move by Russia in that space quite problematic.
The EU is not a military alliance, NATO is. There is a substantial difference between countries being in the EU only and being in NATO (either only or along with the EU.)
EU is economical/societal effort (or war prevention), NATO is military (and doesn't prevent members from fighting, ie Greece vs Turkey). Ever heard of actual EU army? Doesn't exist out there in the world, maybe on paper.
Well, there's Eurocorps for the last few decades, but that's not an army, just a corps-level HQ unit under which component-state forces can be slotted.
OTOH, that's not a particularly poor model for a fairly loose multi-state federation.
On the other other hand, its not actually an EU force, its a force of a particular group of EU states that is made available to both the EU and NATO, and has conducted operations on behalf of each.
Of course it does. Sweden and Finland being members of the EU had absolutely 0 bearing on the US getting involved in a war with Russia. Do you honestly think Russia would've tried to invade Ukraine if they were NATO members?
Given that we (Sweden) have been the preferred partner with Norway for NATO winter training exercises since the 1980s and our entire military strategy was based on "Nato will protect us if Putin invades" you are not wrong.
What changed was USA having people like Trump and the Republican party talk about not protecting NATO countries anymore. It made us realize that we can't continue to count on US help as the premise is based on the US having absolute control of the nuclear weapons, but loading them on NATO ally dual capable airplanes to launch the nukes.
If Europe is not convinced that the US will not share the nukes as agreed, then Europe has to actually rearm and might even casue a nuclear proliferation with France and UK restarting their nuclear programs.
so yeah it changes and not changes the geopolitics.
This is why Sholtz and Marcon are having a bit of a public disagreement.
Germany really do not want to send soldiers to Ukraine. For a whole lot of internal very German reasons their military is not in a good position for armed conflict.
And this one on Germany's very cumbersome procurement tgat is part of why Germany is not keen on rearmament (apart from the obvious: they know what they did) https://youtu.be/8jDUVtUA7rg?si=Du6Rrq2TolbIIaw5
that said Macron is at the moment the only European leader outside of the Baltics that is keen on sending people to Ukraine.
This is what we have to deal with. People believing that when our enemies are arming themselves, it is somehow problematic to respond? This attitude is fading in Europe (thankfully) but I still see this far too often.
Considering the invasion of Ukraine for the second time in 10 years, and the official threats of using nuclear weapons, rearming doesn't sound as bad as before.
> and the official threats of using nuclear weapons
"Why are we shocked? Of course if a country has a weapon it also conceives a situation where it would use it. If a country would never under no circumstance use a weapon it would not have the weapon at all. Every country who has a weapon also conceives a scenario when to use it. Even if they don't issue reminders"
-- My own translation from an interview to Alessandro Barbero
To decomission a weapon is to weaken the army. Rulers must be very careful about taking power from the army, as army officials are wary of being stripped of power. A ruler must be in the good grace of the army.
For that reason, it is difficult to get rid of inherited weapons. A plausible justification is required.
With Putin, however, Russia is strenghtening an army. It is correct in this case, I think, to verbally remind your enemies of the threat they represent. E.g.Trump, in the US, has a strong discourse position to pull the US from conflict, because his supporters want "To make America great again", the world be damned.
I would argue this makes any further move by Russia in that space quite problematic.
