09 It succeeds in defending its national interests by enlisting the support of other nations, forging partnerships and leveraging its ability to influence major issues. Cooperating with partners and maintaining a calm and stable national and international environment has always been a priority for Luxembourg. These Guidelines explain why Luxembourg needs to be a reliable player, both relevant and visible in the field of defence, and lay down the overall directions for the future. They provide a strategic outlook designed to best serve our interests in the pursuit of our long-term foreign policy objectives and of our national and international security policy objectives. A strategic approach guided by clearly defined priorities and objectives enables opportunities to be recognized and seized the moment they arise. These directions will in due course be given concrete expression in a separate document, the Defence Master Plan, which will determine how these Guidelines are to be implemented. The Master Plan will serve as a time line and a tool for implementing the Guidelines, and will be regularly updated. It will be drawn up and supervised by the Defence Directorate, in close cooperation with the Luxembourg army, under the authority of the Minister of Defence. The Plan will enable resource allocation, progress in implementation of objectives, actual results achieved and real progression of projects to be monitored. These two documents will facilitate democratic scrutiny of defence policy by setting out, in an entirely transparent manner, the principles and objectives of that policy. They constitute the baseline for monitoring the utilization of defence resources, the missions of the army, the investment policy and the capability priorities. The Guidelines will also enable our interests to be better promoted in the institutions of which Luxembourg is a member and will explain how the Grand Duchy intends to meet its solidarity-oriented policy commitments as a credible player at the international level.
