Sorry, but lest this is marked as "informative" by anyone due to it coming from a native Hungarian, I'd like to say (as a neighborhood) that this "it's a distraction" sounds like the usual ideas of how goverment works put forward by some blogs, columnists, that are not really grounded in reality.
It's not like Hungary only does "business with the Russians" for the very short term that this will be in the news, for it being a "distraction" to be effective.
It's also not like there would be any popular backslash on "doing business with the Russians" at this particular time either, so that they would need a distraction.
It's more likely that they just wanted an extra tax and some extra dough coming their way, and came up with this, sans distraction nonsense.
