But Poland,Bulgaria, DDR and …Hunguary( damn, the “innocent” victims of Soviets in 1956) have played the very active role in the invasion of 1968.
Except the political support and they voted for the "military operation in Chehoslovakia " when Breznev asced them - What we have to do? - Their troops together with soviet army have entered to the there.
Besides Dani do yo ever know that befor to give the order to enter the the troops , Breznev used the diplomatic channels asced the Washington- what they will do if the soviets enter.
The ansver of the president Lindon Jonson was- the Chehoslovakia is the “inner bisiness” of the USSR.
ONLY after than the troops of Warsaw pact.
Cheers.
