Da group of teeth-grindingly wrathful terrorists whom Doc Brown had tricked into giving him their plutonium with the understanding that he would incorporate it into a bomb that he'd been contracted to build for them, but instead he used said radioactive material to power his totally-for-peaceful-purposes time-machine.
Doc Brown found out da hard way dat da Libyan gnashionalists did not take kindly to having their trust --- and their plutonium --- repurposed in a way they had not intended. Fortunately for Doc, he wore a bulletproof vest da second time, and so things worked out fine in da end... Doc got to power his time machine, and da terrorists didn't blow up innocent people with their "bomb" which turned out to be just a container of old parts from pinball-machines.
