I see the final collapse of the dollar and hyperinflation coming in about ten years, though it could conceivably happen at any time. Throughout history, currencies that have gone into hyperinflation have often done so very suddenly and precipitously.
All of the countries in the world sitting on large dollar reserves are watching them slowly depreciate in purchasing power. As you said, the global marketplace is very dependent on America, and some of these other countries are slowly starting to see that it may not be such a good idea to be so heavily invested in the dollar. As oil and other commodities become more regularly priced in Euros and other currencies, the dollar will no longer be such a highly sought-after commodity. We are not exporting very much ourselves, so right now, the strength of the dollar is tied very strongly to its usefulness in the oil trade...and that usefulness is starting to fade away. At some point, other countries will want to start offloading some of those dollars while they can still buy something of value. In other words, after we inflate the dollar enough, other countries like China are going to cut their losses and bail out to save their own asses, and that will only accelerate the downturn. They'll probably start to do this gradually and covertly, so they don't spark immediate hyperinflation and lose all of their purchasing power or provoke a war.
The problem is, our national debt is horrendous. It's already grown to the point where, even if we started doing everything right today, it would not be fun to start paying it off honestly with regular taxes. Currently, the government makes payments on its debt by borrowing more money, and so its debt continues to spiral outwards. By inflating the money supply to service this debt, we're constantly increasing the supply of dollars, yet the demand for dollars is already going down as more commodities move away from being denominated in dollars. In addition, our government is way too stupid to deal with the cost of our empire, let alone our Social Security and Medicare liabilities. I don't think they will ever "default" on those obligations; rather, they will simply monetize them. Plus, there's always the chance that hyperinflation might occur sometime down the road in the domestic market alone. All of this makes for a dangerous combination, and other countries can see this. They're not stupid: Why do you think we're borrowing so much from China? It's because European banks - our traditional trading partners and allies - have already decided that we're not going to make good on our debt with dollars that are actually worth enough to justify lending. After China stops lending to us, then who will? We might just start printing
all the money we need, and then things will really go sour. Furthermore, each country with large reserves knows that if
another country dollar-dumps first, they'll be screwed.
In other words, each country sitting on massive dollar reserves has a financial incentive to be the first to offload them.
Their desire to do this is being tempered by several factors:
- We may not be an economic giant anymore in most ways, but we are a military giant...and we're such a bully that we're ready to enforce dollar hegemony on the world with bombs.
- They might not necessarily want to piss off their dollar-holding allies by ruining their economies, either.
- Some may be wanting to run the game as long as possible so we rack up as big of a debt as possible...which they then might force us to pay not in nominal dollars but in inflation-adjusted dollars or with real collateral.
The fact is, the United States can only bully around other countries for so long before they decide they've had enough. We're warmongering way too much and pissing off way too many countries, and all of this may eventually come to a head with several countries dictating terms to us as a block (and this might lead to World War III). Russia is already making some moves that are signifying it's not going to take any shit from anyone. China has a huge vested interest in us making good on our debt with something of value, and combined with other countries, they may eventually have the military might to make us. Iran is scared of us and will jump on a chance to join a coalition against us, North Korea would do it just for fun, and we're not too friendly with Syria, either. Recently, we've been making unwanted incursions into Pakistan, too.
Obviously, nobody wants World War III, so these countries are putting off dumping the dollar until they have no other choice or until they have all of their pieces in place. Still...the situation is very precarious for all involved. I imagine this is one of the reasons why the Chinese are pushing for a transition to an international central bank and currency: They're already "in so deep" when it comes to our currency, and now they need a way to secure their investment. In the minds of the Chinese, converting everything to an international currency would prevent the United States alone from inflating the hell out of it all by itself to service its own debt, thereby protecting the value of China's current holdings. It would ensure that everything in the world traded in the same currency (which the Chinese can obtain LOTS of by trading away the dollars they're neck-deep in). This would avoid the otherwise inevitable hyperinflation of the dollar...though in the long run, the new fiat currency would be similarly doomed to failure, of course. In the meantime, we'd see even worse wealth confiscation, only this time on an international level and with nowhere else to turn.

From this perspective, it's not
only the NWO who are interested in a worldwide fiat currency.
The bottom line is: The dollar's fate is sealed. It
will eventually collapse, unless:
- We change our policies, or
- The worst happens and it's converted into a regional or worldwide currency
There are two questions here. One question is, which will happen first? Will a new fiat currency be shoved down our throats, or will the dollar collapse? Of course, a dollar collapse would then also probably lead to a new fiat currency being shoved down our throats, but the difference will be how much different parties "win" from the deal....
Second, when will this happen? You might suggest that this could not possibly happen for another twenty years or more, but I disagree...I believe it is coming much sooner. I'd give it less than ten years, though I could be wrong and it might be much sooner (as I said above, it could possibly happen quite suddenly at any moment or with some significant shift in the geopolitical landscape). I'm not panicking or screaming "The sky is falling!" here. Rather, I'm carefully weighing the factors involved, and the current arrangement does not look like it will last for anywhere near another twenty years.
