How do European leaders feel about their role in negotiations with Russia regarding Ukraine?

European leaders appear to feel sidelined in the negotiations with Russia regarding Ukraine, despite Secretary of State Marco Rubio's denial that anyone is being excluded from these talks. As evidence of their sense of marginalization, European leaders have been conducting their own separate meetings to discuss the situation. This feeling of being relegated comes amid growing pressure for European nations to increase their military support for Ukraine and prepare for potential troop deployments in post-war rebuilding efforts. The UK's Prime Minister has already indicated readiness to put boots on the ground, highlighting the complex dynamics between European contributions and US leadership in addressing the Ukrainian conflict.
