Welcome to 2022, Merkel is retired, for a while now.
Also, yes, EU leaders have been arrogant and weak and completely neglected Russia and especially it's leadership. Since 2013 this outcome could have been prevented and Putin could have been better managed.
Still, nothing gives Putin the right to invade a souverein state just to make his dream of a Sovjet Union 2.0 come true. Nobody wants that not even Kazachstan.
