We heard it about Iraq. BTW, how do you explain the overthrow of pro-American shah by pro-American population?
Machiavelli wrote:
HOW DANGEROUS IT IS TO BELIEVE EXILES
And it does not appear to me to be foreign to this subject to discuss among other matters how dangerous a thing it is to believe those who have been driven out of their country, these being matters that are acted upon each day by those who govern States; and I am especially able to demonstrate this by a memorable example given by T. Livius in his history, even though it may be outside his subject.
When Alexander the Great crossed with his army into Asia, Alexander of Epirus, his brother-in-law and uncle, came with his forces into Italy, having been called there by the exiled Lucanians, who had given him the hope that he could through their means occupy all that province. Whence he, upon their faith and hope, having come into Italy, was killed by them, because they had been promised a return to their Country by the Citizens if they would kill him. It ought to be considered, therefore, how vain are the faith and promises of those who find themselves deprived of their country. For, as to their faith, it has to be borne in mind that anytime they can return to their country by other means than yours, they will leave you and look to the other, notwithstanding whatever promises they had made you. As to their vain hopes and promises, such is the extreme desire in them to return home, that they naturally believe many things that are false and add many others by art, so that between those they believe and those they say they believe, they fill you with hope, so that relying on them you will incur expenses in vain, or you undertake an enterprise in which you ruin yourself.
The previously mentioned example of Alexander is enough for me, but in addition, that of Themistocles, the Athenian, who, having been declared a rebel, fled to Darius in Asia, where he promised him so much if he should want to assault Greece, that Darius turned to that enterprise. Themistocles, not being able to observe these promises, he poisoned himself, either from shame or from fear of punishment.
And if this error was made by Themistocles, a most excellent man, it ought to be considered how much more those men err who, because of less virtu, allow themselves to be drawn by their desires and passions. A Prince, therefore, ought to go slowly in undertaking an enterprise upon the representations of an exile, for most of the times he will be left either with shame or very grave injury. And as the taking of towns rarely succeeds by deceit or by intelligence others within may have, it does not appear outside the subject to discuss it in the following chapter, adding some account of how many ways the Romans acquired them.

1979 revolution was backed by various leftist and Islamic groups.
Remember that President Carter also backed Khomeini, so to speak People werent the only reason to topple the Shah.
