In what ways could Bitcoin prevent "deficit financing of wars"? At a recent NYC Bitcoin meetup, a morally-pacifist, outspoken supporter of Bitcoin said that 


  "Bitcoin would prevent the deficit financing of wars" 


...alluding to his perceived notion that a Bitcoin economy would prevent wars from being funded and started.


Is this a prevailing thought in the Bitcoin community?   
What way of thinking makes this statement appear true?
What aspects of this quote has merit?
There are two meanings to "deficit financing":


Funding something by minting new currency.
Funding something by borrowing.


Obviously, you can't change how fast you mint Bitcoins. Perhaps that's what he meant. It tends to not be very useful, though.

However, it's very possible to have debts denominated in Bitcoin, just as you can have debts denominated in silver or gold. In the Seven Year's War, which lasted from 1754 to 1763, France ran up quite a lot of debt, and they didn't need any of your fancy financial institutions to do it.
