In fact, backward countries are not beaten, what is really beaten is that force is not enough, and countries that are still in strategic positions or have resources! In the world, those southern countries do not look backward and poor, and the US military does not dare to invade them. Because the costs of occupation far outweigh the benefits.
Southern countries mainly include, Bangladesh, Nigeria, Sudan, Mexico, South Africa, Indonesia and other countries. The basic characteristics are backwardness, then poverty, and finally a particularly large population.
Now, not many people in such a country dare to invade. Because, you can't afford to fight guerrilla warfare, don't look at the US military's claim to be the world's largest military power, you let the US military go to calm the Philippine guerrillas, the US military really dare not go.
For these countries, there is no gain from the actual occupation, and it is necessary to control the food and drink, and whoever occupies the final loss loses. If you want to transform management, it is not good to transform, you don't have many resources, you don't have a strategic location if you want a strategic location, you want to work, and you can't do it well.
Therefore, most countries in the South can only serve as dumping markets for cheap goods and second-hand goods for developed countries and manufacturing countries.
