Interesting, though this is the mouthpiece of the Iranian government, which has its own agenda. While Iran has generally been opposed to al-Qaeda, it did cooperate with them for a brief period after the US invaded Iraq (the cooperation backfired when al-Qaeda started attacking Iraqi Shiites):

My own hunch is that the West is clueless, rather than deliberately trying to destroy Christianity in the Middle-East. The US is dominated by ignorant liberal internationalists and neoconservatives who think all you have to do is spread "democracy" and all problems will be solved. They don't realize that most Middle-Easterners are dominated by Islamic ideology and are fundamentally intolerant towards other religions, and that once you give the majority power, they will use it to persecute minorities (look at how Christians are treated in democratic Pakistan). The only hope for Christians is to maintain these admittedly brutal secularist dictatorships who can keep the majority under control.
I think it is interesting that the attacks on Christians have generally come from Sunni groups, not Shia ones. At least in Iraq, I have never heard of violent Shia groups, like the Badr Brigades, carrying out attacks on Christians, and the Iranian government, like the Syrian, is known for tolerance towards Christian minorities (though they're very intolerant of Muslims who convert to Christianity).
