为反击美国，欧洲准备了2套方案

Group 1 - The core issue revolves around Trump's announcement of a 10% tariff on European countries opposing the purchase of Greenland, which could escalate to 25% in a few months, disrupting ongoing trade negotiations between the US and Europe [3] - European officials and analysts are recognizing the need for a strong response, indicating that the EU may have to resort to trade retaliation against the US [5] - The dilemma for Europe lies in balancing economic retaliation with the potential risk to its security, heavily reliant on US-led NATO, creating a precarious situation [6] Group 2 - Europe has consistently stated its position against the sale of Greenland, emphasizing that its fate should be determined by its own people and Denmark, while also participating in military exercises to assert its commitment to Arctic security [8] - The EU is considering two main retaliatory options: reactivating a tariff list targeting approximately €93 billion worth of US products, or employing a new tool called the Anti-Coercion Instrument (ACI) to restrict access for US tech giants in the EU market [10] - The preparation of these retaliatory measures aims not only for revenge but also to enhance Europe's negotiating position ahead of the upcoming meeting with Trump at the World Economic Forum in Davos [10]
