Russia may also station strike missiles on its southern and western flanks, including Iskander rockets in the Kaliningrad exclave between Poland and Lithuania, both members of the North Atlantic Treaty Organization and the European Union, Medvedev said on state television today.
It's about more than missiles.
The underlying issue is the continued independence of Poland and the three Baltic from Russland.
Also, I have wondered if Germany will ever want/ask/demand for Kalingrad to be Koenigsberg again.
