> moral responsibility to help No. No one is saying that. People are saying that Germans should help Greece because it's a rational thing to do. No one, except complete idiots, is saying that they have moral obligation to do it. Here's the quote from OP: > Nonsense! This had nothing to do with moral clarity; it was a rational political and economic decision
Actually, plenty of people are saying that, including the Syriza government who unwisely kept bringing up World War II reparations over the last few months.
I would be very surprised if a person who's so invested in a situation would act intelligently and rationally about it.
