Symbolic of a military strategy for France and Europe that will necessarily put the accent on space and the oceans to meet the challenges of the twenty-first century, the question of aircraft carriers is still generally misunderstood within France’s defence community.

This issue has to be revisited to prepare for the decision in 2011 and avoid making a mistake like the decision on the Maginot Line.
