European Union in June 2026: the most important developments in security
The European Union's security agenda in June 2026 was dominated by the Strait of Hormuz. The EU's diplomatic service proposed that a naval mission take the primary role in clearing mines from the strait, with an expansion of the Aspides mission to Hormuz put forward, and the question was discussed at an EU summit on 18 June. On 9 June US President Donald Trump announced retaliation against Iran for the downing of a US helicopter. On 26 June the EU launched military strikes against Iranian targets following an attack in the Strait of Hormuz.
Defence and the war in Ukraine formed the second theme. The EU held the MILEX 26 exercise, deploying 2,500 troops in Spain to test its rapid reaction force. Ireland set out the defence priorities of its coming EU presidency. Poland spent $16.5 billion in EU-backed loans on heavy army weapons, while Economy Commissioner Valdis Dombrovskis said EU defence spending is nowhere near the projected 650 billion euros. On 8 June defence ministers met to discuss a 6.6 billion euro weapons fund for Ukraine, with a focus on the Eastern Flank Watch. Commission President Ursula von der Leyen said a drone explosion shows the Russian threat is increasing, and the EU presented evidence that China trained Russian troops who later fought in Ukraine. Russian officials claimed that NATO and the EU are preparing for war by a specific date; no independent evidence was provided. The EU was also reported to be considering limits on protection for military-age Ukrainian men.
Borders and internal security made up the rest. The European Commission recommended removing internal border controls in the Schengen area, while officials warned that new EU border checks risk chaos at the start of the holiday season. Montenegro expelled 87 Serbian citizens ahead of the EU summit. The EU approved 100 million euros for the Lebanese Army, EU leaders considered sanctions against drug gangs, and a new Europol report identified the most threatening criminal networks operating in the EU.
