Update: sure enough, here is Ambrose Evans-Pritchard with his own perspective on just this topic, which is oddly comparable to Zero Hedge's: "Mrs Merkel's aides say she is facing "war on every front". The next month will decide her future, Germany's destiny, and the fate of monetary union."

Original:

Every time we discuss the futility of the nth bailout of [Greece\PIIGS\Europe\the Euro] we make it all too clear (most recently here and here) that the trade off between Germany onboarding ever more peripheral financial risk in one after another all too brief attempt to prevent the implosion of European capital markets and its currency, is not only a relentless creep higher in German default risk (and lower in the German stock market, as August has so violently demonstrated) but increasing political discontent, which after claiming countless political regimes across the world, has finally settled down on one that truly matters: that of German chancellor Angela Merkel. And as Reuters reports, Merkel's disappointing response to an ever escalating set of crises, both domestic and international, means that the beginning of her end (and by implication of the Eurozone, and of the Euro) may be as soon as September 23, when the vote over the expansion of the latest and greatest European bailout lynchpin, EFSF, will take place.

To wit: "Germany's Angela Merkel faces the biggest challenge to her leadership since coming to power in 2005, with traditionally loyal conservative allies openly criticizing her approach to the euro zone crisis and her hands-off Libya policy in shambles….it is Merkel's piecemeal approach to the euro zone's worsening debt crisis that has come under fire over the past week and now threatens her iron grip on power in Germany." The biggest problem for Merkel is that she has gone "Japanese" in the opinion of the public: doing neither nothing, nor enough, to halt the European crisis in its tracks: "For some in Germany, she has gone too farby bailing out stricken euro zone members and agreeing to intervention in the bond markets to prop them up. For others at home and abroad, she has not done enough, shirking bold steps that might solve the debt crisis because they would be unpopular at home." This latest attempt to placate everyone, while achievingprecisely the opposite, will come to a head on September 23 when the vote to expand the EFSF takes place: she is for the time being expected to have a sufficient number of votes to pass the critical for the eurozone proposal. "If it's not enough, Merkel would be forced to resign. It would lead to a crisis." And should there be a crisis, it will be the end for the European experiment as well, since with the political situation at the Euro's biggest financial backer in flux, the free fall in European risk will be one that no one, certainly not the ECB, will be able to arrest. Cue even more improvised bailouts by the central banker oligarchy, yet without Germany, the credibility of any and all such deseprate measures will be nil. This incremental political uncertainty will likely make the life of the FOMC's Sept 20-21 meeting slightly easier, as an adverse monetary announcement by the Fed, contrary to that priced in, coupled with the risk of a full blown European crisis, will be very frowned upon by the Status QuoTM.

From Reuters:

Seen for much of the past six years as a reliable, steady leader whose competence and knack for brokering deals made up for a lack of bold vision, Merkel's image has taken a beating over the past months and polls show an increasing number of Germans view her government as directionless. 

The chancellor's troubles can be traced back to two decisions taken in March, when she abruptly dropped her long-standing support for nuclear power in the aftermath of the Fukushima disaster in Japan, and days later backed Germany's abstention from a U.N. vote authorising military action in Libya.
