It was not democratic and Mossadegh was anything but a democrat

He dissolved the Parliament which even a British PM cannot do without Royal Consent.

ROYAL PREROGATIVE: In the UK Only the Queen Can Dissolve Parliament & Appoint Her PM

His hatred of the Pahlavis was rooted in his Qajar Pedigree and loyalties.

Additionally he stood against Reza Shah's Coronation which he never approved.

So this was no Coup but a countercoup

My blog on the subject ( published long before Abbas Milani said the same thing) : 

THE PAST IS A FOREIGN COUNTRY: How Would You Evaluate Iran's Democracy Index in 1953 ?

and another constitutional monarchist view on the subject: 

Khosro Fravahar: Who Betrayed the Constitution in 1953 The Shah or Mossadegh?

By the way if RP approves this CIA revisionist narrative then he is once again betraying his own Father and Dynasty ! 

Yawwwwwnnn....
