The Japanes people have saved money, which the gov't has borrowed. Therefore there was no thread of inflation. Japan wasn't running a stunning CA deficit before the intervention.

Of course the US has to get rid of its oil dependency. Others have to do the same. Do you think Europe has infinite oil under its feet, or Japan, or China?
When you want to invest, you should save. Saving means reducing consume for increasing investment. Why can't the US do the same? Why shall others, who run out of oil in the same time as the US, as oil is globally traded commodity (which means of course the current oil exporters will as well run out of oil in the same time scale), donate capital to the US, while you are running wars, which we don't like (Obama wants to escalate Afghanistan)?
Even in the last quarter, with the the pretty weak dollar (and high competivness) the CA deficit of the US was higher than the pure petrol deficit.
