Krug International, an Ohio corporation, had a contract with Iraqi Airways to build aeromedical equipment for training pilots. Krug then contracted for Power Engineering, an Iowa corporation, to build the specialized gearbox to be used in the training equipment for $150,000. Power did not know that Krug planned to resell the gearbox to Iraqi Airways. When Power had almost completed the gearbox, the Gulf War broke out and the United Nations declared an embargo on all shipments to Iraq. Krug notified Power that it no longer wanted the gearbox. Power sued. Please rule.
