I agree what has been said thus far.
Based on history and normal human inclinations, I see us repeating the 1920's in an economic tradition (meaning another greater "depression/economic re-alignment").
I personally believe that this time is equal to the "Quasi War" that marked the beginning of WW2.
I also believe that Einstein was totally correct when he answered a question: "I don't know what weapons will be used in WW3, but I do know what weapons will be used in WW4-sticks and stones"

I also believe on counting on no one but myself. Anything else that happens along the way, MAY be welcomed (if good) or at least endured (if bad), but I will remain in charge of my own course of action, regardless.

My last word is: keep all things in moderation. Proper planning lets me sleep all night (except for those bathroom wake up calls).
