Next June 6, Europe will celebrate the 80th anniversary of D-Day, the landing that began the liberation of Western Europe in 1944. With Russian President Vladimir Putin advancing in the east and U.S.

presidential candidate Donald Trump threatening to retreat in the west, it's time to think again that perhaps Europe should defend itself. Today, that community is not going to be a single, clear and united institution of the European Union. It will be a lower-case European defense community which will link European, bilateral and individual State capabilities with NATO's military operational base.
