The European Commission has unveiled its White Paper on European Defense, which serves as a framework for the ReArm Europe plan.

Against the backdrop of U.S.-led negotiations with Russia and Ukraine, how might these initiatives redefine Europe's role as a security actor? What will be the immediate and long-term impacts on the situation in Ukraine? Can Europe ultimately form its own security framework without the participation of other nations?
