President Donald Trump's administration released its new National Security Strategy (NSS), which adopts a “flexible realism” doctrine emphasizing shared responsibility and selective global engagement while declaring the USA will no longer "prop up the entire world order like Atlas."The strategy introduces a "Trump corollary" to the Monroe Doctrine to curb migration and drug trafficking in the Western Hemisphere and criticizes Europe for mass immigration, predicting "civilizational extinction" and portraying the EU as an oppressor of freedom.Cas Mudde, an international affairs professor, analyzed the document as reflecting "Trumpism" and European far-right ideology, concluding that the USA now acts as a "willing adversary" to Europe.
