Because MI6 convinced them Mossadegh was a communist sympathizer, and as America's primary European ally the UK's interests are to some extent America's interests. You can read about it but the UK worked on Truman for months.I dont deny we were involved in the coup, as to who was leading is debatable. Why would america, the CIA be interested in a British problem?
I have never shied away from highlighting British failings, Burma, Israel (the whole of North Africa- Middle East) and many more. Indeed, I was told by a poster on here that if I hated my country so much I should fuck off out of it.
The difference between our two countries is we have left our colonial aggression behind. We dont seek to rule the world by organising illegal arms sales to Iran to fund a right wing guerilla war in Nicaragua.
I could carry on naming the many violent interventions by america since the 60's but I won't.
My point is, everyone seems happy to blame trump when every/most US Presidents have been involved in (illegal) military interventions around the world.
I don't agree that the UK has necessarily left imperial aggression behind. There are people in NI and Iraq who would disagree with that among others. Certainly the UK/European ability to project power has changed and you're right that the US has been the primary bad actor since WWII.
