It's not that the other Europeans particularly care about Ukraine. They remember what happened last time they tried to appease an aggressive, expansionist dictator. If Ukraine is allowed to fall then next it will be Moldova, Lithuania, Poland, and so on. Better to take the pain now while the problem is still manageable rather than letting the situation spiral out of control.

Last time it was Germany.

- It militarized Rhineland, nothing happened

- It got Luftwaffe operational again, nothing happened

- It annexed Austria, nothing happened

- It was given Sudetenland, it was even encouraged by allies

- It annexed rest of Czechoslovakia, nothing happened.

- It started war with Poland, Allies declared war and then nothing happened.

- Only when Germany started to conquer Norway, Allies have finally started to wake up.

They can't, with blown up pipes they can't just start receiving gas they need. That gives credibility to this theory - if there are mass protests and new EU governments as a result, they can't go back anyway as there is no longer infrastructure for gas delivery anymore. It really looks like some group wants EU all in, so we should be prepared for the worst possible outcome (WW3, some life remaining on the planet) if that's even possible.
