Since the fall of the Wall and the Soviet Union the West has moved eastwards. Former Soviet states have also moved westwards, some to the EU.
Estonia, Latvia, Lithuania, Bulgaria, Romania, Czechia, Slovenia, Slovakia, Croatia, Poland and Hungary are now firmly in the West.
That eastward and westward movement breaks a promise given by US Secretary of State James Baker to Mikhail Gorbachev in 1990 about NATO expansion.
We are at Russia's border, so it has nowhere to go - cornered rat like - and it, in turn, has Kaliningrad, an enclave from where it could hit anywhere in Europe with its intermediate range (nuclear) weapons.
Let's sit down and talk, eh?
