And what I'm saying is that, the US government will never allow massive deflation such as Japan to occur. They don't need to, since they have the biggest gun in this movie. Who's gonna go and collect debt from an armed thug? Imagine 1 Euro = 50$ US, or 100 YEN = 100$ US - can you? I surely can't. I'm quite sure they will try and invade a few more countries, try and siphon off Venezuela's oil, and keep trying to live on the same pattern of unsustainable consumption at other's expense that they have been used to for decades.
The rest of us are in for a decade of war rather than deflation. Just my 2 cents.
The US government and Fed would love to achieve positive inflation. In reality it may not be up to them. We will see what the markets do.
I don't see how invading small countries or "siphoning off" expensive oil (especially in this market) would stop a deflationary spiral. The US military has done some awful shit but isn't all that relevant here.
The experience of Japan is that no amount of public spending or QE was able to stave off deflation. The same may be true of the US.
