European Union in March 2026: the most important developments in security
France offered in March 2026 to extend its nuclear deterrent to European allies for the first time, after drone attacks on Cyprus that some reports link to the Iran conflict. EU leadership affirmed unity but declined to activate the bloc's mutual defence clause, and NATO and the EU took no formal action. European leaders rallied behind Cyprus on 10 March, and a Spanish warship was set to join the EU's naval shield around the island. Poland announced plans for the EU's first comprehensive anti-drone shield and said it would use EU funds despite a presidential veto on the related spending.
The Iran conflict shaped the rest of the month. Europol warned on 5 and 6 March that the crisis was raising the threat of terrorism, violent extremism and cyberattacks in Europe, and a minister said suspects with Iran links were under surveillance. The EU ordered the evacuation of its embassy in Saudi Arabia, and Romania activated the EU civil protection mechanism to bring home 273 citizens. France proposed extending the EU naval mission Aspides to the Strait of Hormuz, and on 16 March member states were debating its mandate and scope. On 19 March draft conclusions showed EU countries set to strengthen the Red Sea maritime security operation. On 26 March Kaja Kallas accused Russia of giving Iran intelligence used to target and kill Americans, while the Commission proposed a new European intelligence network.
On 23 March the EU opened an investigation into Hungary over reports that Hungarian diplomats, including the foreign minister, briefed Moscow and shared classified EU information. The bloc restricted Hungary's access to classified intelligence and called the allegations extremely concerning.
