Ireland and Greece are only quasi-sovereign as they adopted the Euro; their hands are tied unless they adopt their own currency.
The European Commission, the European Central Bank, Angela Merkel, and amazingly, US Treasury Secretary Tim Geithner have all leaned on Ireland to keep this bullshit charade of paying back all this bank debt.
The IMF and the UK Chancellor are the only external parties who've said there's too much austerity in Ireland and paying off this massive debt pile is not right.
