2019年的欧洲，挑战与动荡持续存在，但也孕育着新的机遇。第九届欧洲议会选举落下帷幕，新一届欧盟机构领导人就职之后，欧洲开启了新一轮政治周期。英国脱欧进入新的阶段，尽管确定性有所增加，但不确定性仍未消除。与此同时，政治极化与分化趋势依然存在，进一步搅动欧洲政治格局，英国脱欧也仍将困扰英国与欧盟的关系。“后脱欧时代”的不确定性与政治分化相互交织，欧洲政治正处在“十字路口”。
European politics experienced challenges and fluctuations in 2019，while new opportunities emerged. After the 9th European Parliament election，new European Union leaders took office and opened a new political cycle. Brexit is entering a new phase，uncertainty is not entirely eliminated while certainties are increasing. In the meanwhile，European politics is still persecuted by political polarization and differentiation，and Brexit continues to stir up the UK-EU relationship. Considering that the post-Brexit era and political polarization are intertwined，European politics is at a crossroads.
