As the NATO summit approaches in Ankara, Germany’s Chancellor is expected to engage with U.S. President Donald Trump on several pressing issues, including NATO funding, Ukraine negotiations, and the U.S.-Iran agreement. With indications that the U.S. may reduce its involvement in Europe, European leaders are tasked with ensuring that NATO’s deterrent capabilities remain intact and that Article 5 of the NATO treaty is upheld by all member states, including the U.S. The outcome of these discussions will be pivotal for transatlantic relations and regional security dynamics.
