The relationship between Washington and Brussels just got a lot more complicated. After the European Union slapped X with a €120 million ($139.73 million) fine for transparency violations, a senior US diplomat decided to connect some uncomfortable dots about who protects whom in the transatlantic alliance.
A Fine That Became a Diplomatic Incident
Deputy Secretary of State Christopher Landau didn't mince words after the European Commission announced its penalty against X. According to Politico, he took to the platform itself on Saturday with a pointed message: "The nations of Europe cannot look to the US for their own security at the same time they affirmatively undermine the security of the US itself through the (unelected, undemocratic, and unrepresentative) EU."
Elon Musk, who owns X and happens to be a major political donor to President Donald Trump, wasn't exactly diplomatic either. He criticized the penalty as hostile to free speech and American business interests, threatening retaliation against what he views as regulatory overreach.
More Than Just a Tech Fine
Landau characterized the X penalty as "the tip of the iceberg," pointing to broader EU policies on climate, technology, borders, and sovereignty that he says damage US interests. In another Saturday post, he framed it as a fundamental question about the alliance: "This inconsistency cannot continue. Either the great nations of Europe are our partners in protecting the Western civilization that we inherited from them or they are not."
He also took issue with European NATO members pursuing defense initiatives without American involvement, calling it a worrying sign for alliance cohesion.
The NATO Spending Conversation Heats Up
The timing is notable. Last month, Secretary of State Marco Rubio was expected to skip a NATO meeting in Brussels, with Landau set to attend in his place, though schedules remained fluid. The State Department declined to confirm specifics but insisted the Trump administration has strengthened NATO relationships and that Rubio maintains regular contact with allies.
Meanwhile, NATO Secretary-General Mark Rutte praised President Trump in June for successfully pushing European allies to increase defense spending. Most NATO members except Spain have signaled support for moving toward a 5% of GDP defense spending target, a significant jump from current levels.
Trump publicly criticized Spain's resistance to the increase, while Rutte reassured allies that US security guarantees would continue if defense budgets rise. The NATO chief has proposed a long-term plan for higher military and infrastructure investments across the alliance.
