“Europe” can manage -
1. the UK is nearly independent of Russian energy
2. France gets 70% of its energy from nuclear power and the rest elsewhere, so nearly independent
3. Poland by the end of 2022 will not import any Russian energy (no Russia coal, petrol or gas).
4. southern Europe is not dependent on Russian energy
5. Scandinavia is not dependent
Only Germany is dependent now
Germany's economy is nearly 1/3 of all of NATO's. Pretty damned significant, I'd say. And it was the Germans who laughed at Trump when he warned about their addiction to Russian fuel.
