since when EU became politically stable? Last time i checked you were at war with Russia.
Russia's attack on Ukraine has no relevance at all to whether the EU is or isn't politically stable.
There may be other reasons you can cite, in which case fair enough, but that example is a non-EU third party attacking a non-EU third party. And the EU is not at war with Russia.
And yes, unfortunately it can't be allowed to persist in its current shape.
But I wouldn't call many EU countries very stable either. It can still be a win to not send private data to the US though, tracking has become far too precise and omnipresent.
