The EU have placed sanctions on Hungary because Viktor Orban won't let illegal immigrants into his country.
The sanctions include cuts to EU funding and loss of voting rights, it's interesting to note that every single Irish MEP in attendance from across the political spectrum voted to place sanctions on Hungary.
Poland has stepped up and declared that they will veto any sanctions put on Hungary.
This is a bigger threat to the EU than Brexit, add to this Salvini in Italy has also threatened the EU with cutting funding to them and it is clear that the wheels are beginning to come off for the EU.
The EU will collapse, it's only a matter of time so it's up to Ireland to decide if we want an organised withdrawal or a chaotic one.
