Allies and paid insurgents are not the same thing. We bought and paid for the Taliban, they were never our friends. But, let's go down the "friend" path. Have you never, ever had a friend change on you? In your entire life, has a friend ever become your enemy?
No matter. It appears you are angry with the United States of America because your ELECTED officials decided to team up the The U.S. and fight in a war that you don't believe in. Why are you blaming the U.S. for a decision that YOUR government made? Do you feel that we (the U.S.) blackmailed or threatened them to join us? If you do, do you have any proof of this?
It's very interesting to see the people of other nations blame the United States for their own leaders, who presumably can make decisions on their own, choices.
