If you are EU-US you want to split the Slavs from Russia so you can't emphasize a common identity. You want instead to play up the "European" identity.
For the Arabs you want to lump those MENA muslims together as a utility 'other'. You can't very well say 'Semites' since you must keep them clear of the Jews. So it has to be Arab or Muslim.
And so it goes according to the whims and dictates of Western (or should that be 'White') imperial politics.
