No, it is something that has been nagging at me for a while. I do have my partisan suspicions, I'll admit that, but I do want to know if there was any other, better reason than just the dumb "party lines" and who was in office while going after Saddam vs Gaddafi (or however you spell his name, I've seen it a billion different ways).
It bugs me, so I want to know more
Let's give you the benefit of the doubt and give you some information.
Yes, there were other reasons than 'who was in office partisan'.
You're right about this: they were both dictators who did a lot of harm.
The first note is that our policy was more driven by our so-called 'interests' than the harm they did. But this is about liberals' opinions.
If you had asked a liberal, should the US support a popular uprising against Saddam with air power to prevent the slaughter of many people, you'd get a lot of 'yes'.
Liberals weren't so crazy about the Clinton sanctions which killed hundreds of thousands of people apparently trying to get them to revolt. That was basically evil IMO.
And on the other hand liberals were wary of war in Libya.
There is a difference between 'intervention' and 'starting a war'. I think the Obama administration was wrong when it tried to claim what it did was not 'hostilities'. But there is a difference - the UN charter has provisions we violated for the Iraq war against starting an aggressive war. If I remember, the UN approved of the mission in Libya.
When Saddam was actually doing the things 'against his own people', the US turned a blind eye, under Republicans, then pulled the killings up a decade later to excuse war.
The action against Qadafi wasn't for what he had done a decade earlier but to save lives.
It's a judgement call that includes a lot of factors, from the justification to the cost.
Iraq was a war IMO that was to give Bush more political power to help him better implements an unpopular economic agenda to redistribute wealth to the top.
It violated the UN charter, killed hundreds of thousands, harmed millions, cost the US over a trillion dollars, and so on, all to 'remove Saddam'.
The calculation was pretty different for Qadafi. For liberals it was more about saving the lives of the people from massacre; the administration likely had its eye on the oil.
But the option there was to save lives with only air power and not ground troops. It made a pretty compelling case not to allow the slaughter to happen.
Things aren't always consistent. A bad or good experience might influence the policy after that, for example.
But I think the Iraq war was perceived as 'starting a war' for corrupt agendas based on lies at huge cost to both sides, while Libya was saving lives for far less involvement.
The people in office may have played a role, but that can be legitimate, whether you trust the person more or less and what you think their motives are.
If liberals thought Saddam was really building nukes to use against us, I think you would see a high level of approval to protect the US from that. He wasn't.
I've long said, liberals didn't really have a good answer about Saddam. Opposing starting a war had its merits - but it would leave a bad dictator in place.
I think there are two sides to the issue. Liberals generally come down against the Iraq war. Most Democrats voted against it if I recall correctly, others very conditionally for it.
