American foreign policy doesn’t have any guiding principle and it never had. Post World War II to this day, they got involved in wars and interference more than any other country. You can’t really say these actions were to support democracy, cause they have supported many dictators. You can’t say it was anti-terrorist cause they have taken side with the worst terrorist. 

If you are not an American ally, you wonder what they stand for. Why was Cambodia bombed? Why are they supporting ISIS and Taliban? Why would you kill so many Iraqi, if the problem is their government?
