The North Atlantic Treaty Organization an intergovernmental military alliance between 30 member states – 28 European and two North American. After Russia invaded Ukraine in February 2022, the Ukrainian government repeatedly requested to be accepted into NATO as a member country. Ukraine’s NATO membership has long been a thorny subject in amongst U.S. government officials due to Article 5 of the alliance’s charter. Article 5 requires the U.S. to militarily defend any member-nation that comes under attack. NATO members countries fear that Ukraine’s immediate entry into NATO — which requires the unanimous approval of all 30 member-nations — would put the U.S. and Russia at war due to Moscow’s invasion of Ukraine as well as its forced annexations announced in September 2022.
