The Adapted Conventional Armed Forces in Europe Treaty is a post–Cold War adaptation of the Treaty on Conventional Armed Forces in Europe (CFE), signed on November 19, 1999, during the Organization for Security and Co-operation in Europe's (OSCE) 1999 Istanbul summit. The main difference with the earlier treaty is that the troop ceilings on a bloc-to-bloc basis (NATO vs. the Warsaw Pact) would be replaced with a system of national and territorial ceilings. Furthermore, the adapted treaty would provide for more inspections and new mechanisms designed to reinforce States Parties’ ability to grant or withhold consent for the stationing of foreign forces on their territory.
