"I say that fundamentals no longer matter when your government can just simply issue trillions and prop up its economy" that is a twisted fundamental.  But the FED has shown printing money does not cause hyper inflation like many have preached.  Hyperinflation has more to do with loss of confidence in a currency over the amount of currency in the system. With the dollar as  reserve currency, it could be the last one standing. 

The euro zone still has many problems not addressed and they refuse to address their problems.  Brexit is happening, Macron whispered a possible frexit  yesterday, then there is  talk of a italyexit. Spain has to deal with a real possibility Catalonia voting to be independent. This would crush Spain and their pension ponzi scheme. Catalonia is the wealthiest state, where losing it´s tax revenue would cripple the Spanish government. 

Germany is facing a pension crisis too. Plus , German elections September 24 2017.  Merkel will probably win, but there is  rising opposition to her reign. A  lot of pieces are setting up for a euro zone storm. In my unprofessional opinion, the euro zone could experience serious problems going into the next few years. There is another problem that will eventually have to be dealt with in Europe.  All the Muslims who have set up no go zones. This will come to a head sooner than later. Especially all the new arrivals. They will most likely be slated for deportation. That will cause severe riots. Let´s not forget the euro leftists who will riot with the Muslims. The EU is a ticking time bomb.

I believe the GBP and Euro will return to their bear market trend, and when they do, the dollar will skyrocket.  

Fundamentals do matter. There are reasons why the dollar could continue to rally in the long term, where metals go sideways to down, because of a strong dollar. Even if you believe the dollar is a turd, it´s still the most shiny turd in town.
