Pan-Slavism in the past was a nationalist ideology that meant taking land from other countries because they were seen as traditional 'Slavic land'. The fears of Pan-Slavism is similar to the fears of a Greater Albania.

It may had been in the past during the times when many Slavic countries were gaining independence. I don't see pan-Slavism as an instent to control more land, although some politicians may use the ideology to fulfill their political agenda.Slavs have plenty of land!

Excuse my arrogance but wtf is 'Greater Albania'?
