“If Europe wants to avoid war, Europe must get ready for war.” That was the warning from European Commission Chief Ursula von der Leyen this month as she unveiled a multibillion-dollar plan to strengthen the continent’s defenses.

It’s an ambitious goal though and one that not all EU leaders agree on. The World’s Europe Correspondent Orla Barry reports.
