I am not sure, whether your figures are accurate. According to the site which you had mentioned earlier (
http://www.nationaldebtclocks.org), the US GDP is $17.418 billion. The net debt is $18.319 billion, so net debt accounts for 105% of the United States GDP. And according to the same site, the Russian GDP is $2.117 billion (the Russian economy is having a significant informal sector, so the real GDP might be much higher). So the net debt accounts for 11.4% of the Russian GDP.
I think that the numbers from Wikipedia are based from a 2012 report. Actually it is, I've just
verified it.Russia actually deceased the dept if the numbers are correct. It was 12.2% of the Russian GDP in 2012.
However, this
link has more 'up to date' information, the numbers don't match now. I'm not sure exactly what to make of this.
Even if we take into account the worst scenario, Russia is still in a better state than the USA. That's 23% of their GDP, compared to 105% for the United Sates.
