I may be stating the blatantly obvious here, but :
1) Neither the US nor any European country, nor the middle east, nor the far east (Abeonomics or not) will ever stop rolling over their debts. Not just because they don't want to. Because they can't. This means interest payments rising at a rate faster than inflation a given.
2) "Real" expenditures (as demostrated by the US shutdown for example) take precedence over loan repayments. As they should.
3) This being blatantly obvious is not stopping a great many people from buying ridiculously bad government debt. The US, all of Europe (not just the EU), Japan and most of Asia with it, are trying to induce inflation by printing exponentially more money over time. It's not working, meaning none of those countries are getting any closer to paying back their debts, even if it was realistic.
1+2+3 = Every country on this planet, with few exceptions, will default on their debts. They may do it by hyperinflation (unlikely, as it will make all of the population very unhappy) or they may just outright default (just makes investors unhappy, and as Greece demonstrated[1], they have very few options left). But there is no way out of this situation that does not involve a large number of government defaults.
We've long since jumped from the plane. And what's this thing coming toward me very fast? So big and flat and round, it needs a big wide sounding name like 'Ow', 'Ownge', 'Round', 'Ground'! That's it! Ground! Ha! I wonder if it'll be friends with me? Hello, Ground!
