You really have got some front. Germany/Angela Merkle's whole plan for buying gas from Russia was if they made Russia a trading partner it would stop Putin being aggressive and invading sovereign countries. A policy you criticised Germany for. Now you take the opposite view point.
And you've made the claim in the past that areas of Ukraine are ethnically Russia as a justification for Russia getting to keep those areas in some forced peace treaty. Now you don't seen to be mentioning that.
It was a solid idea to build economic bridges, the problem is that they went from buying 10% Russian oil to 50%, which was obviously not a good move.
Never said ethnically, not sure what that even means as it's quite obvious people will have moved between Ukraine and Russia for thousands of years, they were mostly Russian speakers in East Ukraine and Crimea however.
