Third, -- and most importantly -- there is every indication the Iranian people hate the mullahs' regime and like the United States.
I recall hearing the something about Iraq three years ago, and it would now seem that many of them hate us too.

It is also worth noting that Hussein also thought that Iranian revolutionary was lacking in support when he started the Iran-Iraq war, after eight years his lack of foresight was painfully obvious. Are we destined to make the same mistake?

I fail to understand why it is that some people think that governments just appear for no reason. The Iranian government may not be democratic but it would not have come into being without the support of a large part of the population, likewise it could not continue without at least the acceptance of most of the people. Finally even if the population was not supportive of the current government there is no reason to think they would be more supportive of one installed by a foreign power.
