Today, we continue to witness the same scene, with all the colonial powers able to take advantage of the crisis by selling weapons to all parties and fueling more religious and sectarian conflicts, turning the entire region into a weapons testing Lab. Is it in the interest of these peoples to devote all their resources to arming themselves to kill each other? As Pooya said, find the beneficiary and you will understand exactly what happened and what is still happening.
This argument is similar to the men who blame the devil for their sins. Each country
country is responsible for their own actions and decisions. If there are two countries at war among themselves, it's because they decided to do so, and not because there is a third country selling weapons to them.
To blame USA for every problems people face in their own countries just remove the focus from the root of the real issues while sounding like an envious and resentmented statement. Probably the first step for third world countries to overcome being third world countries would be to stop blaming USA for their own inability of addressing local issues
and diplomatic questions.
