Ttherefore, Germany should begin aiding these economically troubled countries. Which one of the following principles most helps to justify the political scientist's reasoning? ['Any nation that alone has the capacity to economically resuscitate neighboring countries should exercise that capacity.', 'Any nation that can afford to give economic aid to just a few other nations ought to aid just those few.', 'Any nation that alone has an obligation to economically resuscitate neighboring countries ought to be the only nation to provide any economic aid.', 'Only nations that alone have the capacity to economically resuscitate neighboring countries should exercise that capacity.']
