They chose Russian gas over nuclear. It's not their fault Putin was a madman, but Trump warned them this would happen, and they decided they don't care and carried right on.

I guarantee you if Europe heeded Trumps warning and cut Russia off instead of outsourcing energy production to them, Ukraine would not have been invaded. Even today, there is still Russian gas flowing through Ukraine into Europe. It's unconscionable, and Europeans should be ashamed that they elected such traitors for leaders.

Putin invaded because he thought nobody would do shit, because everyone was signalling nobody would do shit. Biden said he won't do shit and stopped selling weapons to Ukraine and lifted Russian sanctions. Obama did not do shit the last time with Crimea and Donbas. Germans were laughing at Trump who warned them that Putin will start shit if they continue like this, and for the most part, Europeans just increased their dependence on Russian gas.

The moral culpability here could not be clearer. Of course Putin bears ultimate responsibility, but he was empowered and encouraged by spineless corrupt pathetic western leaders.
