Was ČSSR Czechoslovakia? If it was, why the leader of the Czechoslovak communist party at the time, Mr Dubcek, could not introduce "socialism with a human face" into his country in 1968. Why should such a plan provoke the military intervention of the Soviet Union along with its Warsaw Pact allies (with notably Albania among them, as one of the PF member would certainly stress) against the country?
The only problem with that line of reasoning is that if one accepts it, one has to conclude that the country which was in the 1930s where the Czech Republic and Slovakia are now was also not Czechoslovakia, given the way that that nation was unable to put into practice any policies at all in its Sudetenland region and had to accept the loss of that land following the joint Nazi-Polish invasion of the region.
As for Albania taking part in the 1968 invasion, please do stop lying about that: Albania refused to send any forces, just as Romania also did. Only four of the members of the Warsaw pact sent troops to join the Soviet forces invading Czechoslovakia.
