Hungary cannot leave the EU.
The EU has in its statutes that decisions need to be made unanimously.
This is the reason why the EU wants so badly to get rid of Hungary!
If Hungary would leave,
the EU would win.
As long as Hungary stays and torpedoes this decision making rule of needing to be unanimously, in order to get things going,
the EU cannot do what it wants to achieve.
Therefore Hungary MUST stay in the EU, in order to ring it down.
