Occupation of Afghanistan was about Resource Extraction
The latest issue of ULK (#75) was very informative. The article on Afghanistan was a good review of many of the issues.
One you did not mention and that is one of the reasons that China is sending money is that of the mineral resources of the country.
About 8 years ago I had a teacher who applied to work as an analyst for the CIA. As part of his application he did a report on Afghanistan. He found out why the U.$. invaded the country. There are large deposits of copper and lithium ore. The U.$. soldiers were to protect the Chinese workers who were building the railway that would transport the ore into China for processing.
Just like Spain, France, etc. in the 16th and 17th centuries, the U.$. government was in another country to steal its natural resources.
MIM(Prisons) responds: Certainly, natural resources continue to be a major impetus for imperialist foreign policy and war. The gas lines through the Caspian Sea were also a key concern in the region at the time.
Your description of the roles of the Amerikans and Chinese in Afghanistan is emblematic of the relationship between the two countries ever since the capitalist roaders took over in China in 1976. Today contradictions have heightened as Chinese capital has become more developed and therefore needs to exert its interests independent of the United $tates. Meanwhile the Amerikans have begun looking at bringing production and supply chains of basic goods a little closer to home after becoming dependent on the labor of Chinese proletarians. These contradictions playing out demonstrate why inter-imperialist conflict is the rule.
