Today’s security challenges are more complex than ever before and no longer have any regard for national boundaries. They therefore require a global response. As a relatively small country, the Netherlands depends on alliances for its security.

It is based on three pillars: the defense of its own and its allies’ territory, an effective international legal order, and economic security. This article presents the core elements of this strategy, particularly as reflected in the bilateral relationship between the Netherlands and Turkey, two NATO allies.
