I am unfamiliar with the British Chilcot inquiry... but there is no doubt in anyone's mind that Ghaddafi was a very bad man. Reagan bombed the snot out of him back in the '80s over being behind the bombing of a civilian airliner, remember? After that incident, Ghadaffi scaled back his blatant terrorist activities in a big way.
It also sent a message to other like-minded dictators that engaging in State-sponsored terrorism was an unwise move, because we know where you live and have the means to reach you and blow your house up.
So the next course of action for any industrious dictator with terrorism on his mind was the notion of 'plausible deniability' of terrorism via proxies. The palestinians work cheap and don't have much going on other than blowing themselves and Israelis up, so they're a favorite resource - just help fan the flames of religious hate and presto! Instant volunteers. Even better if it's a suicide mission, because it's hard to interrogate dead fanatics.
Saddam knew this, and it was why he was paying the families of terrorist suicide bombers $25,000 on completion of their mission. That's supporting terrorism by any definition.
But there were WMDs found. Lots of them. They're still cropping up to this day.
Remember how the UN inspectors would show up at a facility and were refused entrance while convoys of trucks were hauling loads out of the back? The UN team stood there watching them all leave, then when the last truck left, they were allowed to enter and do their inspection. That happened a lot.
How many UN resolutions can be defied like Saddam did before it's viewed as a useless body? The League of Nations failed because there wasn't any teeth. A stern wagging of the accusatory finger doesn't prevent a ruthless dictator from doing anything.
Beyond that, everyone knows Saddam had chemical weapons because he openly used them multiple times before against his enemy-of-the-moment. Sure, he said he didn't have any, but history said he did.
Bush and Blair (and a great many other world leaders, btw) did the right thing. I'm still bewildered by anyone saying there wasn't any WMDs because they were there and some of them found. Fortunately, there is a shelf life associated with such weapons and soon they'll be as dangerous as baby food in comparison to their original strength, but nevertheless it had to be done.
They didn't lie, and the intel was valid. Iraq has no jurisdiction whatsoever on an American President or a British PM... that's like saying Japan should have been allowed to try Truman after we beat them in WWII. I don't get that line of logic.
The ramifications we're seeing right now is the result of an incredibly incompetent US President who abandoned Iraq and failed to act in other neighborhood situations as they developed. The head in the sand approach while hoping for the best didn't really pan out. Obama left a vacuum and ISIS filled it.
Yes, there are other world leaders that should have stepped up and started fixing things, but that didn't happen either. To be honest, we Americans aren't very confident of European leaders these days to courageously do what needs to be done. In other words, if something needs to be done, it's going to be the USA leading the way and doing the brunt of the dirty work and financing the lion's share of the operation.
We don't want our Soldiers getting killed, and we don't want to have to be the ones killing the bad guys. We don't want to spend hundreds of billions doing it. It gets the USA criticized roundly from the very people we're trying to protect. It's a thankless job.
We'd love to wash our hands of the international problems that crop up because of Very Bad Men doing Very Bad Things, but if you look around the world right now you'll see the result of that approach.
This is a map of where WMDs were found in Iraq :
Here's a few links regarding the WMDs that supposedly were never there :

Here's some in Baghdad being produced in 2013 that were intended for use in Britain :

From 3 weeks ago, Germany reported ISIS used WMDs - possibly from Syria, which is where many convoys of trucks were observed heading from Iraq prior to the invasion :

There's a lot more links you can google up. There were definitely WMDs present and being actively hidden.
