Russia’s annexation of Crimea, military operations in eastern Ukraine, efforts to destabilize the Baltic states and continuous threats to use nuclear weapons against NATO countries has changed the strategic landscape. Instead of out-of-area operations against terrorist groups, NATO is back to its core mission, the defense of its members against external aggression. The playing field once again is Europe and the adversary is the Russian military.
Europe is the main land front again. The Army, backed by air power and sustained by sea power, is what we need there to deter conflict--and win it if deterrence fails.
And put it further east. In corps strength.
And let me repeat, given the geography and opposing force locations, we must accept that we will lose ground if Russia attacks
The key will be to survive losing the first battle and counter-attacking to win the campaign.
