Military over-extension marks the decline of many empires. Currently, the US is a good example.
At the beginning of the Iraq war, Johan Galtung said the war would shorten the life of the US empire with a decade or more, and that may well be true if it’s not an under-estimate. Of course, the decline is and will probably be gradual and somewhat slow with no one obvious ending point.
It’s interesting how many in the US seem to be in denial that the US is an empire, which also means they are in denial of the current decline and inevitable fall of the US empire.
Just to be clear, this is about the US losing its international significance, not the immediate breakdown of the US as a nation. Although given enough time, that too is inevitable, as it is for everything and everyone.
I also wrote about this in my “rants” blog around the time of the GW Bush version of the Iraq war.
Synchronicity: Just after finishing this post, I received an email from Quora where the first question is Will the United States ever collapse? Collapse is a strong word, and a sudden breakdown is possible – given sufficient internal and external pressures, but not inevitable. The way the US comes to an end is more likely gradual, and may involve a separation into two or more sections, or perhaps through nation states eventually becoming less relevant.
