Serbs are domestic Christian Ortodox people (like Greeks and Russian)
Albanians are Muslim illegal immigrants to kosovo (e.i. Serb jerusalem, cradle of ortodox christianity for Serbs, have monasteries that dates from 1200 AD)
Muslim illegal Immigrants, Albanians, are brought by Turkish Muslim opressors during 500 year of occupation, and that was even worstened when Muslim Albaniansy formed nazi SS divisions during WWII, and more worstened doring communist occupation of Serbia 1945-1990 when they actually flooded Kosovo and chased-out majority of Serbs. Crown of islamisation came during Clintons administration wen wollowing 78 days airwar against Serbia, some additional 200,000 Albanians camed from Albania to kosovo along with NARO troops.
in march 2004 Albanians made their "Intifada" burning Churches, buldozing hraveyards, killing and raping with British and german NATO troops just sitting aside and Just French foreinhg Legion and US troops stood against Albanians.
That was in short.
I would say "give them a taste of their own medicine", but that would be too cruel:
What Arab Civilization?
Arabs and Muslims appeared on the world scene in 630 A.D., when the armies of Muhammad began their conquest of the Middle East. We should be very clear that this was a military conquest, not a missionary enterprise, and through the use of force, authorized by a declaration of a Jihad against infidels, Arabs/Muslims were able to forcibly convert and assimilate non-Arabs and non-Mulsims into their fold. Very few indigenous communities of the Middle East survived this -- primarily Assyrians, Jews, Armenians and Coptics (of Egypt).
Having conquered the Middle East, Arabs placed these communities under a Dhimmi (see the book Dhimmi, by Bat Ye'Or) system of governance, where the communities were allowed to rule themselves as religious minorities (Christians, Jews and Zoroastrian). These communities had to pay a tax (called a Jizzya in Arabic) that was, in effect, a penalty for being non-Muslim, and that was typically 80% in times of tolerance and up to 150% in times of oppression. This tax forced many of these communities to convert to Islam, as it was designed to do.
