Turkey has applied to join the EU since 1987, and the two sides are still engaged in difficult negotiations  For strategic reasons, the EU needs Turkey, and a categorical no to Turkey would deprive the EU of Turkish cooperation in security, justice, energy and other areas
However, if Turkey joins the EU, it will bring a series of problems to the EU, such as the disharmony of cultural and religious views, the heavy burden of economic subsidies, and the impact of the influx of immigrants on the job market
In the long run, the EU cannot both obtain Turkey's full cooperation and completely avoid the difficult problems of Turkish membership.
