DislikedWell sounds nice in theory but I disagree with most of your points as they don't match reality.
You are forgetting an important variable in the equation. Is not only debt size but u should include debt and repayment capacity and there, the US, although playing with fire, is by far the biggest economy and the best country (haven) bet to "lend" money short and mid term (25 years span).... Is not my opinion, just look at Treasuries...Ignored
