By insisting on further drastic pension cuts, therefore, the lenders have put Greece in an impossible position (knowingly and deliberately, according to Paul Krugman and other commentators - see links below). The only other option the European side will allow is for Greece to default on their loans and exit the euro – totally absurd, given that there are so many other possible sources apart from pensions for the money for the loan repayments, many of which were proposed by the Greek side but rejected by the troika.
