Ahh poor republican guard,all they did was imprison.torture and kill any opposition to Sadam. they then fought to keep power over Iraq.am sure their were many old scores to settle and ive no problem with it but this was about keeping power over Iraq. these people did go on to form ISIS, it's a shame they didn't wipe them all out.
An oppressive government doesn't fight for democratic elections. the people who fought to stop this happening are the oppressors.
40% of Iraq are Sunnis, if you wipe them all out to create a state that is friendly to the west, you are committing genocide, and that is before you look and see an Iraq and Iran united by religion creating the biggest power broker in the region, and your allies in Saudi Arabia and Israel quaking in their boots at the prospect, so you declare the new shia alliance as terrorism and we go again. Keep throwing fuel on it and wonder why the fire is burning.
Where I do agree is that its a dammed if you do and dammed if you dont scenario, had they left Saddam and the likes in place, you'd be sitting back watching genocides take place.
In the end peace has to happen from within, no western power can create or enforce it.
