it will lose 80-90 billion but no, that wont crush germany. it is just more debt.
Care to explain why this will not crush the German economy? The German GDP is worth some 3 trillion, and the debts by Greee account for almost 3% of it. If Greece refuses to pay the debt to Germany, then 3% of the German GDP will vanish, in a matter of seconds. And considering the fact that the German GDP growth was just 1.6% in 2014, don't you think that this will start a recession in Germany?
