It appears that Putin hopes to engineer a "re-do" of the 1983 deployment of U.S. ground-launched cruise missiles and PershingII ballistic missiles in five West European countries.
In 1983, the issue was whether the NATO alliance would proceed with its agreed plan to deploy hundreds of PershingII ballistic missiles and Ground-Launched Cruise Missiles in five Western European nations (collectively known as Intermediate-range Nuclear Forces or INF).
This may be the most important of these meetings since 1983, when the NATO alliance was confronting strenuous opposition from the last KGB thug to run the Kremlin Yuri Andropov to the American-underwritten plan to deploy PershingII and Ground-Launched Cruise Missiles in five West European countries.
