Out With Pershing, In With Sanity In December of 1987, the US and the Soviet Union signed the INF Treaty. The victims of that treaty were two missile systems, the Pershing IA/II on the American side, and the SS-20 for the USSR. The ultimate winners, or course, are all of us, and a bit more sanity to the world. pershing • missile • ss-20 • inf • treaty

Why Russia (Likely) Won't Go To War Over Kosovo Despite dire warnings from the Kremlin and elsewhere of world war over Kosovo, and despite my own un-Pollyannish view of Russia's potential, I do not believe World War III will start in the Balkans in the near future. I believe this both because Russia has much less stake in the Balkans than in the Caspian, and also because the Russian state is much more stable than it has been in some time. Even the top Communist member of the Cabinet has attacked proposals for "rethinking" Russian military doctrine in the face of NATO action in Yugoslavia. This is more a matter of Russia maintaining some sort of balance of power in the world by siding with America's enemies. russia moscow kremlin yeltsin primakov sergeyev ma
