The most important thing at play is the resistance of Hungary, Poland and others to Merkel/EU demands that they commit suicide through massive Muslim immigration.
I would like to have seen Pompeo make a full-throated defense of Hungary’s right to determine its own immigration practices.
It is Hungary’s prerogative to be part of the EU and endure whatever perks and consequences thereof. Don’t know what their version of a “Brexit” situation would look like.
