Gary Brecher, aka The War Nerd publishing at The Exile, has written a long and fascinating article about the intersection of military and demographic trends in the 21st century. This just sketches out his thinking. I recommed reading the full article.
“War of the Babies–When Modern Warfare and Demography Square Off, Demography Wins“, Gary Brecher, Taki’s Magazine, 6 May 2008
First, he “discovers” the power of weakness. As Martin van Creveld wrote in 2004:
In private life, an adult who keeps beating down on a five year old - even such a one as originally attacked him with a knife - will be perceived as committing a crime; therefore he will lose the support of bystanders and end up by being arrested, tried and convicted. In international life, an armed force that keeps beating down on a weaker opponent will be seen as committing a series of crimes; therefore it will end up by losing the support of its allies, its own people, and its own troops.
Depending on the quality of the forces - whether they are draftees or professionals, the effectiveness of the propaganda machine, the nature of the political process, and so on - things may happen quickly or take a long time to mature. However, the outcome is always the same. He (or she) who does not understand this does not understand anything about war; or, indeed, human nature.
Excerpt:
What was the most important battle of the late 20th century? You could argue it was the one that took place on the southern border of Morocco on November 6, 1975. Of course, we’re not talking about another Stalingrad here. In fact, what happened that day isn’t usually called a battle at all. Its official name is “The Green March.” On one side were 350,000 unarmed Moroccan civilians carrying green (Islamic) flags, and on the other-miles inside the border, because they were hoping not to have to confront any of the marchers - was a shaky, demoralized token force of Spanish troops pretending to defend a former Spanish colony, the Spanish Sahara. … The Moroccans had to think outside the traditional military-conquest box, for the simple reason that Morocco’s armed forces are pathetic.
