What is the advantage that American gains?

Question

from involving themselves into current issues in Afhganistan, pakistan, Iraq ( in economics, politics, etc) ? Because American, more than any other countries, seems to put a lot of efforts in those issues

Answer 1

America gains nothing but power over those third-world countries where the governments of those countries just give in to American government as they have no power to use against America. And if any of the countries try to stand up to America, they get accused of something illegal like the Iraqi leader Saddam Hussein and you obviously know what consequences he has been put through as well as its country though they have nothing but hatred for American government for what they did to Iraq.
