"President Donald Trump is scheduled to meet with NATO heads of state and government in Brussels on May 25, 2017. This will be the President's first collective meeting with his counterparts from NATO's other 27 member states. President Trump is expected to continue to strongly urge NATO members to increase defense spending and enhance military capabilities. For numerous reasons-not least the United States' status as the world's preeminent military power-U.S. defense spending levels long have been significantly higher than those of any other NATO ally. Since NATO's founding, successive U.S. Administrations have characterized a steadfast U.S. commitment to NATO as essential to advancing a key U.S. security interest: peace and stability in Europe. Nevertheless, the relative imbalance in defense spending and military capabilities within NATO has long fueled concerns about burdensharing and European allies' reliance on U.S. defense guarantees."
