Massive European immigration to Palestine

Folks, pay attention. This post is about massive European Muslim immigration to Palestine :

One source cited for this information is NITLE Arab World Project:

The Balkans, too, were a source of Muslim out-migration. With the disintegration of the Ottoman Empire and the establishment of Greece, Serbia, and Bulgaria, about 1 million Muslims, some speaking Turkish, others not, moved east to remain in the diminished empire. Many of those who settled in Turkey assimilated, but some village communities persist in retaining a distinct identity (Palaczek, 1993).

Let's see now...how many Muslims came to Palestine, and what do you think the possibility is that their numbers inflated the Muslim population figures at the time?

Here's more evidence of Muslim immigration, from Caucasus Foundation:

Circassians arrived at their present location from Balkans in year 1880 after 10 years of residence at Marvel-border of Greece and Bulgaria, they migrated to Palestine, the Holy Land of the three monotheist religions. Ottoman Sultan asked them to reside at Rihania (Reyhaniye) and Kfar-Kama villages.

Both sites indicate there was European immigration by Muslims around the same time as Zionism started up, coming from two sources that can hardly be considered Zionist.

Here's the clincher:

The inhabitants of Palestine are composed of a large number of elements, differing widely in ethnological affinities, language and religion. It may be interesting to mention, as an illustration of their heterogeneousness, that early in the 20th century a list of no less than fifty languages, spoken in Jerusalem as vernaculars, was there drawn up by a party of men whose various official positions enabled them to possess accurate information on the subject. It is therefore no easy task to write concisely and at the same time with sufficient fullness on the ethnology of Palestine." -- Encyclopedia Britannica, 1911

So, I'm wondering ... how is it exactly that Jews are European invaders to Arab land?
