Meanwhile, there is this thing called the European Union. Both Romania and Hungary are members of it, for better or worse. The border between Hungary and Romania is becoming increasingly irrelevant, and with Romania's (and, btw, also Bulgaria's) imminent entry into the Schengen system, the whole thing will be pretty much completely meaningless. (To get a sense of what's going on on the ground: Since the introduction of visa-free access to the west European parts of the EU for Romanian citizens, the real problem for the Hungarian labor market is not the massive influx of informal labor from Romania, but the opposite, its disappearance. Romanian citizens, who had been a fixture in seasonal agriculture as well as the construction industry until about 5-10 years ago, have more or less moved to richer EU-member states.) Be that as it may, the border is all open, especially for Magyar-speaking citizens of Romania.
All this border revision talk is basically a red herring.
So, OK. I think I get it: the guy is a provocateur, he thrives in stirring irrational sentiment. Just ignore him.
What I don't get is why he does not get ridiculed out of politics.
