Imo you guys should read this
http://www.theguardian.com/commentisfree/2015/jul/17/germany-greece-wolfgang-schauble-bailout And then realize something... this German government
never wanted this bailout. It raised the stakes to something it considered impossible for Greece to agree to, in order to get the result it wanted ( A voluntary grexit). A Greece agreeing to the 3rd bailout terms and austerity measures was not what Germany wanted and hence not something Germany worked towards in the negotiations
post referendum and the shitstorm that happend with the 2nd bailout negotiations. For Germany, Greece was already out of the Euro at this point (in terms of realpolitik goal).
The idea of a temporary grexit (which would have turned permanent) was the last olive branch extended to Tspiras to grasp to not lose face. Instead he opted to agree to an Austerity package literally nobody in Germany expects to work. And over HALF of all Germans
didn't want either.
Politics are always messy and dirty.. but imo it's clear that you can't blame Germany for trying to get Greece to accept reality that Bailouts aren't going to solve the problems. The idea of the temporary Grexit did come from Schäuble, after all. And France+Italy were starkly against this. So Greek people.. by no fault of your own you ended up in a mess where France+Italy forced Germany to raise the stakes in negotiations because it never wanted a 3rd bailout to begin with.
This is what they mean with "considerable rift" between France and Germany btw. There were literally 2 mutual exclusives ideas here and even goals at work.
*** Makes for a nice conspiracy theory anyway ***
Ps.: There is no danger of WW3 ;) European Union is stable and the economically the most powerful united entity on the planet. There will be wars coming when oil crisis starts, but western nations already have ability to turn to electric cars and renewable sources if they really wanted. Plastic can be made by other materials. But other nations, that can't do such massive infrastructure changes would be pretty much SOL.
Never got why people fear WW3 anyway. That world war would be the one with nukes. And who the hell cares about a war with nukes? Not like you or me are gonna survive even the first exchange. So why worry? In true Strangelove mantra: Embrace the bomb ;)
