There's a lot going on behind the scenes that's not reported. Never was a fan of nation building or any US involvement in the region, unless absolutely necessary. Back in the late 70's our family moved to the Middle East as expats. Lots of Americans, Brits, Germans and others quietly living in the region working on major projects like infrastructure, building military installations, enlarging ports and of course oil projects.
IMO the issues of Iraq, Afghanistan can be traced to the 1991 Gulf War and the fall of the USSR as well as a number of other factors. The 1991 Gulf War gave the impression the US military power was dominant and could be used for purposes that were deemed appropriate and for the "common good" You had ultra-conservative, think tanks pushing for a more aggressive US foreign policy. Washington DC is a swamp run by lobbyists and think tanks. The PNAC (Project for a New American Century) took hold in 1997 a good number of the original signatories were part of the cabal that started the Afghanistan war and regime change in Iraq. Many were also talking heads on US media. All they needed was a catalyst to put their theory into practice. 9/11 was that catalyst.
The 1991 Gulf War also shook off the post Viet-Nam caution with regard to use of the US military.
Once the war in Afghanistan was started its was difficult to stop. As the old saying goes, wars are easy to start, but difficult to end.
At this time China was a third rate power. In time US business interests, hungry to access the vast potential of China, started pushing a policy with the thesis of "as China becomes more capitalistic, they will become more democratic....
Its also hard to ignore the role of money, the vast industrial-military complex that exists in America. A lot of people have become very well-off with the profiteering from the drawn out war in Afghanistan.
In the early 70's Nixon took the US off the gold standard. The US-Saudi petrol dollar agreement was instituted. Oil would be priced in US dollars and the Saudis would use their new found vast wealth to invest in the US. US arms sales to the region as well as the world is astronomical.
Like the war in Iraq, the war in Afghanistan was never paid for. It was put on the credit card. While waging 2 enormously expensive wars the US instituted tax cuts. The current US deficit is calling into question the use of the USD as the global reserve currency. 2 major bailouts via stimulus packages only adds to the fire.
My belief is if you are wise and prudent you begin planning on how you will navigate a world where the USD is not the once all powerful dominant force in the world. With it also goes the military power that has been funded by America abusing the power of the US dollar as the global reserve.
Some believe gold/silver is the solution, other say crypto is. One thing is for sure....change is coming.
