So the West should just let Russia invade Ukraine? The reason Japan attacked Pearl Harbor was because of the oil embargo, sure. But the oil embargo was in place because of their aggression against China. Should the US have kept selling oil to a country that was killing 100,000's of people in China? If is, where is the line drawn? When should the US have stopped supporting the Japanese war(which is what they were doing by selling the oil needed to carry it out)?
