…unless they also condemn the USA for invading Afghanistan, Iraq, etc.
Most European territories serve the USA’s geopolitical goals. Sanctions against Russia right now are part of that. There’s nothing moral about it. It’s simply a service to the USA for being in its sphere of influence. There is nothing, not a single shred of integrity in that.
If you find a territory which sanctions Russia for its crime, and also the USA for its crimes, you can recognise it as a real principled act.
It’s hard to be sure what’s going on behind the scenes. The only thing we can be sure of is that there is a lot going on behind the scenes.
To me it’s pretty clear that this big reaction to the invasion is driven by the USA. The USA has a huge political influence in (at least western) Europe. That can be proven by examples only.
The reaction has been so consistent between all the countries, it must be driven by a single powerful influencer. Otherwise there would normally be disagreements, oneupmanship, the usual.
But other interpretations are possible. What makes you believe the one you said?
