The Russians waged a four hundred and fifty year crusade against Islam, although we do not recognize it as such. Had it not been for the Russian resistance from 1444 up to 1918, the whole of Russia would have been Muslim today.
The Russo-Turkish Wars were a series of ten wars fought between the Russian Empire and the Turkish-ruled Ottoman Empire during the seventeenth, eighteenth, and nineteenth centuries. Their conflict during World War I should also be counted as an eleventh and, so far, the last Russo-Islamic war in the series.
Such was the indomitable spirit of the Russians that for four centuries together they did not give up the struggle till they finally destroyed the Jihadi threat to not only to Russia but also to Europe from the East.
They made the Invading Jihadi Turks eat crow and made Turkey the sickman of Europe.
