It thinks that supporting Putin's genocide in Ukraine is some how going to revive the fascist Greater Serbia dream. Completely detached from reality.
There was some muppet Serbian politician, I can't remember his name, who said that Croatia will only be as big as what you can see from the cathedral in Zagreb. That is a great example of the delusional Serbian superiority complex at the time. Worked out well for them.
Interesting to know that Serbia has sold massive mounts of ammunition through third parties to Ukraine. Hats off to that Serbian loyalty to their Slavic Russian brothers. Who needs enemies with friends like that.
