I hope Hungary will not get financial aid from IMF and ECB (if I remember correctly) or will make it extremely hard to get it. That will harm Hungary in short term but in long term it will be good for all the Europe. It will send very good signal for all other Europe countries where right-wing extremists do stupid things (especially Eastern Europe).
P.S. I'm from Eastern European country and I see some similarities with Hungary.
I would like even more the EU to have a direct way of dealing with this kind of situations, but for now I agree with you - that's the fastest way to pressure the Hungarian government.
