In a pivotal EU summit, European leaders, prompted by escalating threats from Russia and uncertainty over U.S. military support, have committed to a substantial increase in defense spending. The summit, attended by Ukrainian President Zelenskyy, marks a watershed moment as leaders unveil plans to spend €800 billion on defense and bolster support for Ukraine following a U.S. aid pause. The urgency of the situation is underscored by rising fears of a security vacuum, leading Europe to take decisive steps to rearm and ensure its own defense capabilities. While the new spending plans aim to unify European defense strategies amid the backdrop of shifting global alliances, skepticism remains regarding their immediate impact on the ongoing conflict in Ukraine.
