There have been plenty of nations who have predicted the fall of the US, and pretty much every other world power for that matter. It's sort of like end of the world propehecies, if it ever happens, chances are it will be on a date that someone predicted.
The problem with this prediction in paticular is that it's simply too soon, states the wrong reasons, and makes the assumption that certain world powers would be a factor in absorbing US territory that never could be, and even if they tried, would probably themselves end the US's breakup since an external threat is the fastest way to re-galavanize a people, especially if this is happening so quickly.
I point a finger at things like him claiming that Japan or China would take over Hawaii. More likely China would wind up invading Japan since the two nations hate each other, relations are only somewhat cordial because the US uses Japan as one of it's major naval bases and our foothold/tripwire in the Eastern World. That's one of the reasons why you don't see more anti-Americanism than you do from Japan, they realize that if we weren't there no "SSDF" or military they could rapidly put together after our departure would stop the payback parade. China, Korea, pretty much everyone in that region would want a piece.
Mexico is just going to come into Texas and take it over, just like that? Umm yeah, okay. I really see that one happening. Maybe they could take it eventually, but it would be a fight.
What's more it seems to be based on power fantasys/cultural self-validation. When someone starts talking about "moral collapse" as a motivation for a nation falling apart it generally means that someone is talking out of their rear. Also our economy and standard of living is still one of the most powerful/highest in the world, like anything that could change, but not instantly.
Now, one point that can be made about the US that is more valid is that by all rights we have the perfect formula for a civil war. In fact any other nation would have already had one, which is what I think bugs a lot of theorists and why a lot of people hate the US, we routinely do things that should be considered impossible. Simply put the US is contineuing to function with a society that is polarized pretty much 50-50, and for a long time now we've been seeing our leaders be elected with disturbingly small percentages of support. For example when Obama came into office with 57$% of the vote, that mean that 43% was against him, and that's a staggeringly small number for something like this. What's more the two major schools of thought in this country hate each other, and are in constant battle about almost everything.
In pretty much any other goverment a transition of power from Clinton to Bush and then from Bush to Obama would not have happened peacefully with the numbers being what they are. We've more or less made something work that no other nation has been able to, and that pretty much blows peoples minds.
The thing is that for all the arguements about gay rights, national policy, etc.. Americans have a pretty strong identity, and agree with enough things on a fundemental level where there aren't any disagreements stong enough that are leading to the average joe picking up a gun and going after the other side en masse.... and we're better armed (on a per-citizen basis) than most nations. Other nations just don't get it, especially seeing as they couldn't keep going in situations like this. Laziness isn't there, it's just that our society was designed to always be in conflict with itself to some extent, and for nothing to get done easily, and for the most part there is no real issue that has angered anything but a fringe to the point where they are willing to head out with machine guns and pipe bombs to try and kill the other side.... partially because we specifically built our goverment with enough checks and balances that even if you killed The President, or took out most of Congress, things would still keep going. The amount of damage you'd need to do to force a regime change (effectively) would be staggering and by that time there wouldn't be much of a nation left, and even most of the potential whack jobs realize that.
Ahh well, enough rambling. I suspect we'll be here through 2010 just fine.
On the other hand the US will eventually fall. It will likely happen two ways: One, due to not acting quickly or pre-emptively we're destroyed by a rising foreign power after a war, China is the current potential culprit for this given their build up and the issues involved. Two, we disband the US ourselves as part of acheiving a global unity, when other nations dissolve into a world goverment, so do we.
