Legalization of gay marriage is not among requirements for countries aspiring to join NATO. To join the Alliance, nations are expected to respect the values of the North Atlantic Treaty, and to meet certain political, economic and military criteria, set out in the Alliance’s 1995 Study on Enlargement. These criteria include a functioning democratic political system based on a market economy; fair treatment of minority populations; a commitment to resolve conflicts peacefully; an ability and willingness to make a military contribution to NATO operations; and a commitment to democratic civil-military relations and institutions.
