Antall and the dissolution of the Warsaw Pact

A disputed theological point has been raised, perhaps inadvertently, by three centre-right Hungarian MEPs, József Szájer, László Surján and Péter Olajos.
They organised a meeting to celebrate the decision to name one of the wings of the Parliament's palace in Brussels after the late József Antall, who was Hungary's prime minister from 1990 until his death in 1993. In the notice of the event, they described Antall as “the man who initiated the dissolution of the Warsaw Pact”.
Success, they say, has many fathers. So too has the pact's dissolution. Probably there is not a single political group in the Parliament (certainly not the EPP-ED) which could agree on who initiated the dissolution of the Warsaw Pact. Still, worth a try.
