Explaining that the cost of US government debt is falling because interest rates are falling doesn't change the fact that as a proportion of GDP, servicing that debt is lower now than it has been since the 1960s.
You assume that when the recovery comes and interest rates increase that the US government will not be able to service its debt.
You forget that if-when the recovery takes place (and that wont be anytime soon while government remain deluded by "expansionary austerity") the GDP will grow and so will tax revenues. Part of those increased tax revenue will meet the increase cost of the debt, and maybe pay some of it off (as happened under Clinton).
If I was allowed to cherry pick and analyse data in isolation, I could prove that my mother is the Queen...
