NATO is required to protect each Alliance member. Based on current political and military conditions in the Baltic States, NATO can no longer successfully deter Russian aggression as revealed by recent open source war games conducted by RAND. NATO would be left with nothing with bad options if Russia pursued a campaign similar to its efforts in Ukraine. Therefore, NATO must continue to adapt to the 21st Century and a resurgent Russia. This adaptation would include a military force capable of deterring Russia’s Western Military District, broadening its exercise program, and a earmarking a force capable of relieving the deterrent force. These military options would be supported by a NATO information campaign and political commitments. NATO must consider Russian interests and how best to work with and around President Vladimir Putin’s current administration.
