As for NATO, it’s better for the big countries if they can hold Russia back in the Baltics and let them be the collateral damage. Sounds win-win to me.
And they get access to lots of cheaper labour directly (migration) and indirectly (outsourcing to people that will still buy your stuff).
As I’ve posted, the big banks in the Baltics are primarily not Baltic.
That access has its benefits, but also its price.
I guess I’m a believer that free trade works out well, well enough to create a system to support those left behind. Often the latter is left out however.
