Hmmmm, yes but in one month of Afghan against Afghan fighting over 50,000 civilians were killed.
With US weapons, training and finance... They left the country saturated with guns... Since you mention...
US pumped money and arms to Aghanistan for a decade to crash the Soviets without the slightest concern of the Afghan people. Once they did the job they were disposed by the US just like a plastc razorblade...
With US help the legit government had been replaced with drugtrafficing criminals who wrecked havoc to the country for years, they were so bad that the Afghans found that even the Taliban were better than them.
Now the US putting back the same guys to the neck of the Afghans... Remember: the Taliban banned the opium growing, the Northern Alliance, the latest friends of the US already started to get bookings for the next year harvest...
Not to worry anyway, by the end of the winter the 50.000 dead will be surpassed - thanks for the US help. Technology can do great things.
