Per Wikipedia: There are an estimated 500,000 Muslims in Ukraine and about 300,000 of them are Crimean Tatars.[252] There are 487 registered Muslim communities, 368 of them on Crimea. In addition, some 50,000 Muslims live in Kiev; mostly foreign-born.[253]
Ukraine has an approximately 1% Muslim population (using your numbers), including those living in Crimea. According to the CIA world factbook, Russia has a Muslim population of approximately 10-15%. As there are many Putin cheerleaders here (not you) insinuating against all logic that Ukraine is a Muslim country, I thought I would provide these figures for comparison.
Okay, in your mind all muslims are terrorist and that’s another reason that Putin should mistreat these people who’ve done nothing to him or Russia. So just say that and be done with it.
