"OUR" country will feel consequences too if Russian doesn't lose

Thats the point. Beimg nationalist is not completly wrong, because you still live in your country.

But I a country just looks for itself, it doesnt blend out all the other countries and the problem they have. Our world is interconnected like in no time before, wd cant just shut our eyes and try to be happy.

And as germany is the biggest economy in Europe, we should be more supportive than economically smaller countries
