History shows that he Inca Empire grew by invading other nations.
If the people of an invaded nation resisted the aggression, the incas proceeded to cut their supply of water. Thus, the choice for the victims of aggression was either to die of thirst or to surrender.
Nowadays, the imperial power grows by invading countries rich in natural resources.
When the people of a nation resist the aggression, the imperial power attacks with an economic blockade, which does the following:
– It cuts the means for the people to acquire food, leaving them with the choice of starving to death or surrendering.
– It cuts the means to acquire medicines, leaving them with the choice of dying of illness or surrendering.
