After months of planning and campaigning I get to enact my revenge for the humiliation my ancestral homeland suffered at the hands of the US invasion decades ago. With glee, I watched as the deadly neurotoxin was loaded onto the missile which would disperse the vile substance in the atmosphere. Millions would die, a just revenge at long last.
