Well the good news is Brussels can't bully Poland so easily given Hungary has said it will veto Article 7, and if they don't do it then other allied states will. Next big EU split is West vs East, especially when all that British cash dries up and they don't have a big enough bribe for France *and* Eastern Europe. I think we can assume Paris will demand the money and won't take no for an answer-the French talk of "Europe" only when it suits them, just look at Macron. Talked big about how pro-European he was during his election campaign, then just weeks after getting elected blocks the Italians from buying French infrastructure and goes protectionist.
I think the only solution to the EU budgetary crisis post-Brexit is to do what they always do and squeeze the Dutch a bit more. They could probably get a majority of countries in favour of that (and if Duuring doesn't like it the Dutch can always leave).
