Further, the link you sent does not say the Greeks do not have to pay back the debts. It says that they have "suspended interest payments for a decade" and that they "gave Greece more time to repay." In other words, they pay back the debts over a longer period of time. Not that they start in 10 years.
From the Wikipedia: "21 July 2011 in Brussels, where euro area leaders agreed to extend Greek (as well as Irish and Portuguese) loan repayment periods from 7 years to a minimum of 15 years and to cut interest rates to 3.5%" Nowhere do I see information indicating that "they don't have to pay back the debts." Quite the opposite, the Wikipedia page says what I told you earlier: that the "bailout" is to avoid a Greek default. i.e. a failure to pay back. As far as I can tell, only you are saying that they are not currently paying back. But then again, I'm a fool, so what do I know?
