The EU has entered a 'rearmament era' to support Ukraine and ensure strategic autonomy. A five-point plan, 'REARM Europe', aims to mobilize €800 billion over four years, primarily through increased national defense spending. The plan includes borrowing from capital markets and activating the national escape clause of the Stability and Growth Pact to allow higher defense spending. Additional measures involve mobilizing private capital and adapting the European Investment Bank's mandate. The EU is also exploring long-term options to enhance defense capabilities and establish a 'rearmament bank' with non-EU countries.
