The Expansion of NATO (North Atlantic Treaty Organisation) in the post-Cold War led to the changing of the European security architecture, involving Moldova (RM) in a new security system. Moldova is placed in a position to choose from three alternatives: - maintaining the permanent neutrality of a multidimensional foreign policy; - plenary participation in the Euro-Atlantic structures and strengthening dialogue with the U.S.;-membership of CIS’s defense structures and strengthening military cooperation with the Russian Federation. At the same time we can not adopt a passive position in security issues, demanding protection from any threat to our partners but with no contribution from our country’s part.
