From the National Interest: NATO has become the worst example of America’s junior-high foreign policy. Washington and its more traditional allies have welcomed a succession of new members which are security black holes, bringing with them geopolitical conflicts rather than security assets. Little pretense could be made that expanding NATO to Albania, Romania and similar states enhanced American security.

Even worse are proposals to add Georgia and Ukraine to the alliance. Both border Russia, have unresolved or potential territorial disputes with their nuclear-armed neighbor, and are politically immature. Bringing them into NATO would directly challenge Moscow’s border security and turn American foreign policy over to smaller powers of dubious reliability.
