Some people are reading way too much into that cable. They are taking it as a sign that nothing happens that the US doesn't dictate. Of course, the US tries to manipulate everything. It works all the angles it can see and concerning which it has the resources to deal with, and people should be mindful of that. There are independent actors in the world though.
Also, just because the US works angles doesn't mean that some of those aren't improvements. Should there be a democratic global revolution? Does it have to be "democratic imperialism"?
By the way, contrary to that article, this idea is not new at all. It's at least as old as neoconservatism, and I would argue much older.
Regardless, there are multi-track criticisms going on about the US. One of them comes out from a group that despises democracy on any level and a subset that does so more than do the others. That's the group to watch out for the most. It's very stealthy, and many of its minions, including a number of intellectuals, don't even realize when they start working things in ways that benefit that elitist-of-elitist group.
It's not a hard and fast line of demarcation that one may point to such that everyone will instantly see it. What it is though is what lies at the core of the individual members of that group. Either they have self apart from God there or they have the wholeness of God that is the one soul of humanity. The best way to judge that is by the fruits they bring forth.
If they are bringing forth death of fellow humans (particularly the innocent) or wanton destruction or pollution, one may be certain they are not of God. If they excuse such behavior and advocate for it or secretly desire it, they are not of God.
Of course, it must be said that instigation versus defense are relative offenses. The instigator, the oppressor for evil, has the greater sin; and "evil" there is properly defined as ultimately the more selfish and harmful position to the whole being — the one soul.
Who is representative of this subset I mentioned? Ayn Rand would be a prime past example. She hated the spirit of Jesus Christ to an extent that cannot be overstated.
To be clear, I am not saying that the current iteration/common notion of democracy is God or that Jesus condones coercive democracy. Democracy can be demon-crazy, and Jesus was opposed to humans coercing one another. What he wanted and still does (he lives) is a consensus of all humanity centered on his teachings and life example, which would bring Heaven to Earth in full and would save the world from the other world, the current one, the one ruled by the spirit of Jesus's arch enemy.
