This is opinion.
There is an old Indian classic about a guy called Mahawshadha and his opposing kings adviser called Kewatta. There was a war, and the story about Kewatta's war strategy is famous. Some time ago there were two telecommunication companies in the U.S, Ma bell and AT&T. Ma Bell was a smaller company but they gathered their market following this same strategy. This is such a big story that even in marketing it can be adopted.
So Kewatta's strategy was to go to smaller kingdom, tell them that we will annihilate you if you dont submit to us and give us your power, but if you submit, you are not plundered and you are all good. You live, we are just a little more powerful. So they go on doing this with all the kingdoms in the region, one at a time. Small to big. If you understand this methodology, this is exactly what the Taliban did.
Can you blame the U.S and Biden for this ultimate aftermath? Not so sure about that. I think they had to leave eventually, some day. Blaming game or not, one has to acknowledge what took place on ground. In the country, the Taliban is known to bring peace and that's exactly what they did earlier after the Russian departure. They bring peace and stability, but not prosperity and freedom. This has been their legacy, and those people who thought the new Afghan regime were all good in terms of freedom, there was war, bombs here and there, and corruption everywhere. Thus, the peasant type's who yearned for stability and freedom put their hand in the left and right hands of the Taliban. Done and dusted. This will never mean freedom. Maybe to some, but not to all. This is very well known. The Taliban played their game very well and the rest of the world watched TV and made their own juices based on the cordial provided therein.
The conspiracies behind the Opium, the oil pipe, and the trillions spent on the drain are all super tools to use for pleasure, but none of these bring anything to fruition now.
Nevertheless, I would like to understand what you thing would be the next step. What can anyone do? I will truly appreciate your valuable insights and feedback.
Peace.
