This document, issued by Charter 77 spokespersons Ladislav Hejdánek, Marta Kubišová, and Jaroslav Šabata on the 10th anniversary of the 1968 invasion, provides a rigorous legal and political critique of the Soviet military presence in Czechoslovakia. The signatories assert that the intervention by five Warsaw Pact nations was an illegal act violating international law, the UN Charter, and the Helsinki Final Act. The statement focuses on deconstructing the justification for the "temporary" stationing of Soviet troops, which was originally based on the alleged threat of West German militarism. The authors argue that since relations between the Soviet bloc and the Federal Republic of Germany were normalized through various treaties in the early 1970s, this justification is no longer valid. The document calls on the respective governments to withdraw the troops and address the damaging internal political consequences of the occupation. It also notes the solidarity of exiled Charter 77 members in Vienna who demanded the release of political prisoners and an end to discrimination.
