This looks like small potato territory to me.
Greece was in far worse shape (and still is) and the solution was additional loans. In the Greek case, the loans were not so much borrowed, as rammed down the throats of Greeks. They were forced to borrow via threat essentially of an oil blockade — that inevitably leads to starvation. The EU, ECB and IMF told them you WILL take these new loans, you WILL use this money to bring the old loans up to “current” status (meaning payments made on time, NOT retired), and you will do it no matter what your silly popular referendum says.
Ukraine will be forced to take loans to make payments on the old loans in exactly the same way — and it will be reported as salvation and success, and the additional loan burden will be waved away as inconsequential.
Which, btw, is why oil is everything and money . . . is printed from nothingness by central banks.
