Tell that to the passengers and crew of Pan Am 103. Oh, wait, you can’t, because they were killed by terrorists trained and supplied by Muammar Gaddafi.
Hell, Gaddafi spent years as a one-stop shop for terrorism, not only financing his own anti-Western terror attacks (such as bombing a nightclub in Germany and the previously mentioned bombing of Pan Am 103 over Lockerbie, Scotland, killing 270 people), but he also financed myriad other anti-Western terror groups ranging from the P-IRA (which killed over a thousand during the period), the PLO, and other terror groups. Basically, if you were willing to bomb Western civilians Gaddafi was willing to fund and even supply you (much of the P-IRA’s explosives they used to blow up pubs in the UK were supplied by Libya).
As for how they ran Libya: I’ll never understand how anyone who claims to support even basic human rights can defend regimes like those of Gaddafi or Assad. These are people who, when faced with peaceful protests, ordered their soldiers to mow down the crowds with automatic weapons fire. Nothing can justify that, and you should be ashamed of yourself.
