The Afghanistan situation is indefensible. It is a prime example of "if you do not learn from history you will be doomed to repeat it". Everything our military brass said about the Afghan army the said about the South Vietnam army in 1970. The only question is, did they really believe that BS or were they just saying it to avoid having to admit Vietnam was a failed 10 year exercise that cost 50,000 American lives? Now, in 2021, can the military responsible for training the Afghan army admit they failed after spending hundreds of billions or US dollars to get it done?
Furthermore, we had the more recent lesson of Russia in Afghanistan. Another important lesson not learned due to arrogance and politics.
Getting out of Afghanistan was the right thing to do, just 18 years too late. And think about this, if Trump had not won in 2016, we would probably still be there for another 10 years or more. Trump just pulled the plug on a never ending war that had no real mission goals. To paraphrase the movie War Games, the only way to win an endless war is not to fight one.
The Biden team is attempting to shift the issues from HOW we withdrew to whether or not we should have withdrawn. No one is questioning the should we. They are asking legitimate questions about how we did it because it is to total sh-t show now. Worse, they are all lying about it. The Pentagon is blaming the state department, Biden is blaming Trump, and so forth. The issue is, who concluded the Afghan Army was a viable fighting force? He/she should be fired. The issue is, why withdraw troops before civilians? Again, the responsible party should be fired. The issue is, why leave advanced military equipment behind to fall into the hands of the Taliban - and most certainly Russia and China. Billions of dollars in research and development were wasted.
So many lessons from history have been ignored and now we are going to pay a very high price. After 20 years, we are right back where we started and no better off.
