Exactly, and bonds are included in government debt. Hence this statement is wrong:
> Government debt have no interest
Also this statement is also wrong, since government bonds aren't money in circulation:
> National debt is simply the amount of the national currency in circulation.
Another proof about this statement being wrong: Sweden has currency worth just 1.26% of GDP in circulation, but about 35% of GDP in debt. If what you said was true that would be an impossibility. You are trying to spread falsehoods and even contradict yourself, that is a fact.
