That's...mostly irrelevant. Yes, government interest payments would be inflationary because some of them go back into the domestic economy, but flooding the domestic economy with money through loose monetary policy is not net deflationary; the reduction in money pumped into the economy in interest payments is far less than the amount of money that is pumped into the economy to effect that reduction.
