2022年2月，俄罗斯对乌克兰发起特别军事行动，以捍卫其传统势力范围。俄乌冲突的爆发，意味着冷战后欧俄和美俄关系范式的终结，法国从对俄接触派变为对俄遏制派。俄乌冲突的激进性、聚旗效应和代理人战争属性驱动了法国对俄政策的“时代转折”。不对称的核威慑博弈、大国冲突导向的混合战对抗、以退为进的局部战线收缩是法国对俄政策逆转进程中的三大特点，而“持久战”化、核竞赛化和“亚太移植化”或成为其三大演进方向。
In February 2022，Russia launched its special military operation against Ukraine in defense of its traditional sphere of influence. The outbreak of the armed conflict spelled the end of the post-cold war European-Russian and American-Russian relationship paradigms. France has since jettisoned its engagement stance and opted for containment. The drivers behind the Zeitenwende of French Russian policy are arguably threefold，namely，the radicality of the Russo-Ukrainian conflict，the rally-to-the flag effect of such armed conflict，and the proxy war dynamics inhering in the same. The Russian policy reversal by France stands out for its three-pronged response，mixing nuclear deterrence maneuver，hybrid war confrontation and local retrenchment. Such policy U-turn is likely to exhibit a trio of development trends，namely，a metamorphosis into a “long war”，the unleashing of a global nuclear arms race and a replication to the Asia-Pacific.
