I don't think name calling the EU as bullies advances anything. It is unsubstantiated and sounds like political speak and click-bait.

The problem of unsustainable debts of EU countries is complex. Debts cannot be fully forgotten as this sets an unsustainable precedent. Full austerity isn't sustainable either. Any reasonable solution will be nuanced.

By the way the same issue will arise soon enough to another EU country or to some US state. Will the US feds be bullies by telling states their debts cannot be forgotten?
