0h 27min, nov 27, 1958 y - USSR issued the 6 month Berlin Ultimatum

Description:

This was the demand of the withdrawal of forces from Berlin to make it a free and neutral city. This was to get the West to negotiate to the future of Germany and Berlin, or the USSR would sign a treaty with the GDR which would threaten the Western Powers.
This would cause the West to deal with and recognise the GDR which would make the Hallstein Doctrine irrelevent.
