It's a complex issue, whether the US has done more good than harm; in regards to the Middle East at least; is certainly up for argument. Their interference has caused a lot of problems.
The Iranian coup in 1953, orchestrated by the CIA and MI5, was the beginning of very strained relations. A coup organised over oil removed a democratically elected secular president. The region would be a tad different if Mossadegh had remained president.
Just an example of a stuff up from the West.
**Not that that justifies things currently happening there, but there has to be acknowledgement of what the West has helped cause**
