I found Hugh Hendry panel on the Milken institute quite informative. His thesis is that austerity will go on until the people just won't take it anymore and then the people will pretty much force the governments hands
I checked Bernanke's book 'Essays on the Great Depression' to see how Germany, the supposed inflationphobes, behaved and whether they reflated. The answer is, it took time, they weren't quick but eventually they initiated very reflationist policies(1934, but specially 1936) by effectively removing themselves from the international gold standard.
In 1932 and 1933 German suffered severe gold outflows which can impact the money supply if the central bank is committed to a gold standard. Thats what happened. Gold reserves plunged and they allowed that to affect their money supply(by not doing enough purchases and increasing the monetary base and M1)
If you look at the charts you can see that gold reserves did only one thing which was to go down(Q gold), yet starting in 1934 M1 started to rise EVEN THOUGH the money multiplier fell(M1BASE). This suggests QE like activities where most of the money sits on the banks but the part that goes out increases the money supply(Thats the part that people who say QE doesn't work, miss), among other inflationary policies
So forget their dogma. All a country need to devalue is enough pain. Keep in mind that the above reflationist policy happened a little over a decade after hyperinflation and yet they STILL did it
Does that mean the German will lead devaluation?Probably not because their economy is just fine and there is just not enough pain there. But the other countries are almost certainly lying when they claim they won't leave the euro no matter what
The political 'will' to keep things together just need a low enough GDP in order to be broken
