Nah, embargo/blockade Hungary. Hungary is almost completely surrounded by EU members who its reliant on for its economy. They need to have elections and get rid of their dictator if they don't want to be turned into European North Korea.

And (if Erdogan wins reelection) sanction the crap out of Turkey. Turkey's economy is in the shitter and heavy sanctions would make them think twice about stirring the pot. Their elections are already heavily manipulated by Erdogan, and can hardly be considered free or fair. Hope we get some international observers to help confirm the results in May.
