Yes... its no longer "role-playing in the near future", but is now "role-playing in an alternate history".
That would be fine to me... I could even run it as "Twilight 1995".
This would use an earlier POD/trigger, and require fewer updates of equipment beyond what is in the rules and various supplements.
This setting would reverse the "China-Soviet first, NATO intervention in the German-WP dust-up coming later" sequence of the 1E setting.
The scenario is that, when Gorbachev had let the WP nations start to go in 1989 (
Hungary and
East Germany), the Communist Party had overthrown and executed him, and had then tried to re-assert their control, beginning when the Soviet-backed
Socialist Unity Party of Germany (SED) lost the
general election on March 18, 1990.
This would cause West Germany to initiate NATO/WP hostilities, with the war in the West developing from there.
Since the
Soviet-Chinese talks over the
disputed territories were a project of Gorbachev, the Central Committee and the Supreme Soviet would denounce and terminate the negotiations and re-assert its claims to all the territory.
The Chinese then would try to seize not only these territories but to reclaim its historic holdings in
Outer Manchuria while the Soviets were distracted and tied down in Eastern Europe.
This way the war would start in 1990, the Chinese would come in in 1991, and by 1995 the general situation would be pretty close to the 1E setting (although 5 years earlier).
