To the extent that Americans (or anyone else) believe "Democracy is like giving a lollipop", they are *wrong*, irrespective of the rationalizations you suggest.
Emergence of democracy requires the presence of solid institutions like a functioning and stable law and order apparatus, an independent judiciary, a fair legal system and constitution, and a solid corps of civil servants.
It's not enough for Americans to imagine that they're offering someone a chance at the "democracy-lollipop". The chance offered is a farce, unless Americans also take sensible steps to cultivate the said institutions which the Bush Administration has not done.
Indeed, in such cases, a grandstanding "promise of democracy" could easily be a slogan to distract, while you pursue other goals (oil, geopolitical influence etc).
America having badly failed to create institutions needed to sustain democracy, it makes no sense for you to rationalize that the failure is not that of Americans, but that of the people who want to be "hesitant to taste" democracy.
It is simply dishonest to blame the victim for American failures.
