The EU leaders are meeting in Cyprus to discuss strengthening European defense, particularly focusing on Article 42.7 of the EU treaties, which could serve as a mutual assistance clause. The urgency of this discussion has increased due to US President Trump's threats to withdraw from NATO. Cyprus President Nikos Christodoulides emphasizes the importance of this clause for non-NATO member Cyprus, especially after recent drone attacks. The summit will also address the war in Ukraine, energy crises, and a two-year reform plan for the EU single market. Additionally, the EU is working on unblocking a €90 billion loan for Ukraine and imposing new sanctions on Russia. The European Commission is urging measures to support vulnerable groups facing high energy prices due to geopolitical tensions.
