are essentially worthless
The EU's stick and carrot is not all that new, in fact it has existed since the dawn of civilisation. It was used by monarchies and republics, religous denominations and atheists, rightists. leftists and anyone else in power. Putin's Russia also charges different prices depending on how compliant and pro-Moscow the client countries are. Incentives, disincentives, rewards and penalties, deterrents, pressure, blackmail -- it's all old hat!
minimum expectations
Siding with one faction of an internal dispute was never stipulated in any of the EU treaties. Is telling a country how to run its court system and what to legislate those minimum expectations? Even the Venice commission insisted that parliament started the trouble and parliament should resolve the issue. If it wasn't for the sntichers' brigade, the Schetynas, Petrus and Kijowskis regularly embarking on snitching expeditons to Brussels, Berklin, Paris, Washingtion and lobbying for outside intervention, this whole mess would never have occurred.
