The destruction of the Caliphate marks the end of the implementation of Islamic sharia in all aspects of life and the cessation of the spread of Islamic treatises throughout the world with da'wah and jihad fi sabilillah.
The event also caused major changes to the international political order. Since then, Muslims have virtually no influence in the international world. Even at a certain level, Muslims are just the object of the game and the conspiracy of rotten Western imperialist countries.
Thus, the collapse of the Caliphate has been the culprit of all calamities, crime, sin and destruction for Muslims
