Why may the debt crisis be only "sleeping" rather than "dead?"

What will be an ideal response?

Debt restructuring has postponed but not eliminated the need for eventual repayment, and
a small share of debt has actually been written off. It remains to be seen whether indebted economies have reformed sufficiently and will operate in an economic climate that enables the debts to be repaid. See section 13.4 (especially page 693).
