Deal on Greek debt crisis exposes Europe’s deepening fissures

Together with the migration crisis and Greece, these represent “the four horsemen” circling around Europe’s future, said Rem Korteweg of the Centre for European Reform, a research institution based in London.

“The four horsemen threaten the EU precisely because they raise issues that can only be solved if governments prioritize a European solution over narrow national agendas,” he said. “If a European answer cannot be found, the horsemen will continue to promote chaos, instability and mutual recrimination” within the European Union.
