Russia and China are aligned with Iran and those three will be soon aligned with the EU...just how in the world does that qualify as backing Christianity over Islam?
Exactly right, Iran is strengthened and increases as a thorn in the side of the US and antisemitic Western Europe, Muslims are stronger and cause more trouble in Russia's competitors (or enemies if you wish)
...just how in the world does that qualify as backing Christianity over Islam?
In Eastern Europe and Russia there is strong government support for Christianity, driving Muslims, especially terrorists to emigrate West. Russia is making their territory Christian and exporting misery to their competition.
Russia and China have Muslims killing Muslims in Syria and won't allow NATO to come in and save the lives of the Muslim Brotherhood like in Egypt and Libya. Which policy gets more and the most dangerous Muslims dead, and divides their forces? Which policy kills Coptic Christians or Jews?
