Hungarian government spending of the EU funds is gonna get investigated by the EU Commission. Probably not the Commission itself, but some committee entrusted. The result would be cutting EU funding. The whole thing is called "rule-of-law standards" investigation, and justified by the claims about rampant corruption. To be honest there is rampant corruption.
On the other hand I suspect corruption is just the same (or even bigger) in the rest of the EU, I guess the main difference is that while Orbán and co. passes all the fat EU money bags to their friends and family, in the civilized west those in politics aren't the ones who are doing favors due to their own authoroty, they just puppets of influental interest groups and economical powers. Besides would anyone give govt funding to those who aren't in bed with them, for those who are closer to the opposition?
Here the opposition bitch an moan about the corruption, but they did the same, and would do the same.
The result will be the same as with the sanctions. Putin now can point to evil west how they want to choke Russia, and he can be the hero defending the nation. Orbán can (and will) do this too (actually continue to do this), the champion of the people who stands up for them against evil Brussels. And he'll need unifying words and every bit of support, because the economic situation now isn't a joke, and the treatment won't be pleasant. But he'll be able to conveniently shift the blame to Brussels for every inconvenience, and strict measures.
Problem is Hungarian citizens and entrepreneurs will drink the black soup.
I wonder how much the HUF will fall by tomorrow morning.
