Of course, there are two important differences: the Iranian public is currently more pro-American than it was in 1953 (especially Iranian youth) while the army is more anti-American. However, these two factors do not cancel each other out; while the former makes a coup slightly easier, the latter makes it significantly harder. Nonetheless, there are many Iranian politicians who would stand to benefit from American intervention -- namely, Ahmadinejad's opponents, the opponents of the clerical system, etc.; moreover, Mosaddegh was far more popular in 1953 than Ahmadinejad is now. If the US would can economically isolate Iran, putting additional stress on its already shaky economy, it can create the necessary turmoil to destabilize the current regime and attempt a coup (cf. Chile, 1973).
There are certain factors that render a coup more difficult to effect than it was in 1953 or 1973 (for one, the greater decentralization of the Iranian military), but if the US plays its cards right, it may usher a more amenable government into power.
Alternatively, if the US is willing to adopt a strategy that has a greater chance of success but is more time-consuming, it can wait until the reform movement seizes power. Then, it can provide economic support to Iran to allow the movement to consolidate its power until it is able to win the allegiance of the military, at which point democratic governance will be discontinued. The downside to this approach is that it is uncertain whether the reform movement will be able to ascend to power. Perhaps a good example of a failure of both approaches would be Cuba; initially, the US attempted to stage a coup in Cuba, but was thwarted in its attempt. Later, the US tried to destabilize the Cuban regime through sanctions; however, given its past behavior in Cuba, it was unable to obtain any significant amount of leverage with the people or government of Cuba. As such, Castro's regime has managed to maintain its grip on power for several decades, while the US can only wait for the wounds of the past to heal and a reform movement to gain momentum.
