The good news is that it's now OK to say this on FR. A decade ago, it would have got me banned.
The persecution of Christians really started back in ‘03, clearly it wasn’t as bad as what was to come with ISIS; but it still happened.

A lot of sources say this. Everyone can research it for themselves. And it goes without saying, there was already some persecution of Christians while Saddam was in power. But it became a huge disaster.
