They are divided. Part of them believes NATO propaganda and another part is very upset with the criminal attack on Yugoslavia. Yes, I heard my Polish friends mentioning the Glivice provocation as an analogy to Racak.
But, me personally I see rather analogy with 1938 when International Community helped Hitler to "liberate" Czech Kosovo - Sudetenland inhabited by the German majority. After Czechs compromised soon Hitler devoured the rest of Czechoslovak Federation.
The same propaganda about Czech atrocities against ethnic Germans as was against Serbs in Kosovo. Only difference was that Czechs gave up without a fight.
