European Union in April 2026: the most important developments in security
In April 2026 the European Union's security agenda was shaped by the war involving Iran and the Strait of Hormuz. On 3 and 4 April Iran shot down two US aircraft, and the EU and China called for an immediate ceasefire and safe navigation in the strait. On 7 April the EU urged the United States not to commit war crimes in Iran as a deadline approached, and asked member states to prepare for security threats from the Middle East. On 12 April President Trump announced that the US would take control of the strait and block Iranian ports, and the EU warned Iran about ships near the waterway. By 14 April the EU reported that no ships had crossed. On 17 April EU leaders were planning a defensive mission to secure the strait after Iran reopened it, and on 23 April the US sent a third aircraft carrier to the region.
The second theme was European defence and Russia. The EU put €115 million into projects under its AGILE programme on artificial intelligence, drones and quantum technology and was reported to be spending more than $1 billion on defence research drawn from the war in Ukraine. Spain's Prime Minister Pedro Sanchez called for an EU army, and the head of the European Defence Agency said member states could reinstate conscription. On 21 April the EU was reported to be preparing tens of thousands of soldiers for Ukraine, while Estonia announced the training of tens of thousands of Ukrainian soldiers. A leaked audio recording published on 8 April had Hungarian Foreign Minister Peter Szijjarto offering an EU document to Russian Foreign Minister Sergei Lavrov; he did not comment.
Inside the bloc, the new digital entry-exit border system became fully operational on 10 April, with 27,000 travellers reported blocked. Czech authorities carried out arrests and raids in an EU subsidy fraud case on 8 April. On 20 April the US and the EU imposed visa restrictions on 75 people linked to the Sinaloa Cartel.
