Germany underwent a profound transformation, termed "Zeitenwende" by Chancellor Olaf Scholz, following Russia's invasion of Ukraine on February 24, 2022. Foreign Minister Annalena Baerbock noted the end of old certainties, prompting a fundamental reorientation of German security and defense policy. This involved a €100 billion special fund for the Bundeswehr, a commitment to invest over two percent, and later five percent, of GDP in defense and strategic infrastructure, and permanent troop stationing in Lithuania. Germany also abandoned its restrictive arms export policy, becoming a major supporter of Ukraine with over €50 billion in military aid and €40 billion for civilian projects. The nation grappled with domestic debates, refugee integration, and economic impacts from energy price hikes and sanctions, learning to avoid dependencies and take threats seriously.
