Despite his bombastic rhetoric, Donald Trump's administration took significant actions to bolster Europe's security during his first term as president. These actions included strengthening NATO, increasing military exercises, and providing advanced weapons to Ukraine and Georgia. Trump also criticized the Nord Stream 2 pipeline and imposed economic sanctions on companies involved in its construction. However, the geopolitical landscape in Europe has changed dramatically since Trump's first term, particularly with Russia's invasion of Ukraine. The biggest question now is how Trump will handle the war in Ukraine and craft a coherent policy. European leaders are focused on working with Trump's second administration and are in a stronger position with increased defense spending and commitment to their own security. The future of transatlantic security depends on both Trump's actions and Europe's ability to meet new geopolitical challenges.
