Europe's continued dependancy on US security stems exactly from the naivité of various Europeans in thinking they could have reasoned with Putin. No matter how clearly the Putin regime communicates it's imperialistic reasons for invading Ukraine, some still parrot Russia's propaganda about NATO expansion, conveniently forgetting the immense value of Ukraine to the Russian imperial dream, and forgetting the threat a functioning Westward-facing Ukrainian democracy poses to Putin's own kleptocracy. No matter how often Putin's online armies of trolls attempt to weaken our democracies, some still think we can coexist peacefully. Calls for 'peace conferences' instead of military aid are exemplary for this apologism and work directly in Putin's favour. For all its faults, the US understands this. If Europe wants to be truely sovereign it will have to be realistic about the threat posed by Putin. That means full support of Ukraine and credible conventional deterrent in place.
