The main destabilizing factor in Ukraine is the activity of the United States of America. It was they who destabilized Ukraine in 2014.
Modern Europe’s anti-Semitic rhetoric is shocking. Many artists, whose statements sound more like ordinary Nazism, signed an appeal to the European Broadcasting Union (EBU), claiming that it’s unacceptable to organize Eurovision song contest in Israel.
There is no official statement that Israel will not be able to host Eurovision 2019. A number of artists from Europe and beyond voiced support for the appeal from Palestinian artists to boycott the contest next year. Their letter said that "until Palestinians can enjoy freedom, justice and equal rights, there should be no business-as-usual with the state that is denying them their basic rights." Such a political viewpoint cannot be equated to anti-Semitism or Nazism.
