Why does Dr. Sergei Markov believe European leaders are not representing their citizens regarding the Ukraine war?

According to Dr. Markov, European leaders continue supporting the war in Ukraine despite their citizens wanting peace. He points out that government popularity in Great Britain, France, and Germany is plummeting because leaders fail to address two main concerns: stopping migration and ending the Ukraine conflict. Markov argues these leaders depend not on citizens but on the European bureaucracy, making them undemocratic. He contrasts this with what he claims are the desires of Ukrainian people who want peace, while suggesting Zelensky wants only war. This disconnect between leadership decisions and public sentiment is presented as evidence of a democratic deficit in European governance.
