Don’t they mean the palisteeniuhn problem? FTEU. Europe was a lot more fun when it was a bunch of different countries.
It wasn’t a bunch of different countries for very long, though. The EU, no matter what its name was at any point in its history (starting in 1951 as the European Coal and Steel Community), was always virulently anti-Israel.
The Palestinian problem is that the Muslim calling the shots among the Palestinians or gleefully following the program won’t live peaceably with others.
