French President Emmanuel Macron is rallying Europe to load its "big bazooka." The EU is considering activating its anti-coercion instrument for the first time, threatening massive counter-tariffs on US goods if Trump proceeds with his Greenland sanctions.

The instrument, designed for bullies, allows the EU to freeze access to its lucrative single market. "If we do not bite back, we will be eaten," a French diplomat warned. The stakes are high: a trade war would hurt both sides, but Europe seems decided that sovereignty is worth the cost.
