In 2005, France rejected the proposed European Union Constitution, which could have marked the beginning of the political unification process. Successive French presidents have declared that France will not accept a United States of Europe as even a remote goal of European politics.
目前法国是欧洲军事最强大的国家，它反对一切将欧洲武装力量集中起来的建议。1954年，法国国民大会拒绝了西方联盟防御组织（Western Union Defense Organization）。2005年，法国拒绝了欧盟宪法草案，该草案意味着政治统一过程的开端。此后各位法国总统宣布法国不会接受欧罗巴合众国，哪怕将此作为欧洲政治的遥远目标也不行。
