The Soviet answer on 4 May admonished Tito and the Communist Party of Yugoslavia (CPY) for failing to admit and correct its mistakes, and went on to accuse them of being too proud of their successes against the Germans, maintaining that the Red Army had saved them from destruction. Tito's response on 17 May suggested that the matter be settled at the meeting of the Cominform to be held that June. However, Tito did not attend the second meeting of the Cominform, fearing that Yugoslavia was to be openly attacked. In 1949 the crisis nearly escalated into an armed conflict, as Hungarian and Soviet forces were massing on the northern Yugoslav frontier. On 28 June, the other member countries expelled Yugoslavia, citing "nationalist elements" that had "managed in the course of the past five or six months to reach a dominant position in the leadership" of the CPY. The assumption in Moscow was that once it was known that he had lost Soviet approval, Tito would collapse; 'I will shake my little finger and there will be no more Tito,' Stalin remarked. The expulsion effectively banished Yugoslavia from the international association of socialist states, while other socialist states of Eastern Europe subsequently underwent purges of alleged "Titoists". Stalin took the matter personally and arranged several assassination attempts on Tito, none of which succeeded. In a correspondence between the two leaders, Tito openly wrote:
