"We will, in fact, be greeted as liberators" - Dick Cheney (but I'm sure it'll work out this time)
There is a whole lot of directions this can go after we arrest the dictator, but a liberal democracy magically immediately popping isn't on my list. There might be one in the future but there will be a lot of chaos and violence between now and then.
For some reason he thought it would apply to Islamic theocracies and it clearly didn't. Pattern matching Venezuela against Iraq or Afghanistan is an obvious mistake.
(tho not sure how much we can really trust what he says)
Those countries were actually being liberated from a foreign power that had invaded them just a few years prior.
There are very few examples where a foreign nation overthrowing the indigenous government (no matter how despised that government may be) are greeted as liberators, and in those select few instances the sentiment is almost universally short lived.
