Again. None of that means Saddam should have been left alone to carry on his killing and persecutions
None of it means the US/UK/the West should be allowed to take it upon themselves to remove someone from power either. We are not the world police, we don't get to decide what is right or wrong for other nations, and we certainly don't have the right to destroy a country and kill millions of innocent civilians in the process to do it.
You're implication that it was 'all about oil' is specious. China got the oil.
Indeed it does. It's also a huge country with a massive and well equipped military and a population with a shared culture and history spanning thousands of years. I imagine the risk/success assessment for trying to overthrow the Chinese regime and install western ideals was somewhat unfavourable.
I also didn't suggest it was all about oil, I suggested oil was a primary driver. There were undoubtedly other considerations too. But let me ask you this, Saddam was committing atrocities for decades before we finally removed him, his genocide took place in the late 80s, why did we leave him in power until 2003?
If we removed him then purely for altruistic reasons why ignore the other atrocities and genocides happening at the same time? If it was a fear of wmds, why not go after other rougue nations? If it was a fear he might supply terror groups, again why do we ignore other nations doing the same? (also we're quite happy to supply/fund terror groups ourselves so it's massive hypocrisy if that was the reason).
Incidently you also stated earlier you felt Saddam would have supplied terror groups with weapons if he'd been left alone and I have to wonder whether you realise that Saddam was actually suppressing alot of these groups?
Al Qaeda, for example, were been operating since the 80s and had even offered to defend Saudia Arabia against Iraq after the invasion of Kuwait. They were enemies and considering how saddam treated his enemies I can't imagine he'd happily hand them over weapons they might use on him (unlike the West who were more than happy to provide what would become Al Qaeda with a whole range of weaponry).
