Brian Whitmore: Warsaw, son of Wales
US troops land with parachutes at the military compound near Torun, central Poland, on June 7, 2016, as part of the NATO Anaconda-16 military exercise.
In many ways, Warsaw will be a sequel to Wales. Two years ago, NATO was in emergency mode. Today it is planning for a long and tense conflict. Two years ago, the Atlantic alliance went back to basics, refocusing on its core mission of defending its members. Today it is methodically putting the pieces in place to contain and deter an increasingly revanchist Russia.
