Return of an ideology
Ideologies do not end by the downfall of the states which embrace them, even if this downfall leads to the break-up and fragmentation of the states. This is what happened with Marxism-Socialism; all the nations and people which the Eastern camp was composed of abandoned it, and turned to Capitalism to build their lives upon it. So, the collapse of the USSR in the early 90's was not just the break-up of a state; it was the failure of an ideology.
Thus, in terms of universality, two ideologies remained, Islam and Capitalism. However, Islam did not become eliminated with the downfall of Khilafat in 1924 . Islam still remains a living ideology as more and more people are embracing it and shaping their lives according to its basis. However, because of the conspiracy of the West and their agent rulers in Muslim lands, Islam has been reduced to rituals only.
Realising these facts, the Muslims in many places have started to convey the message of the religion including the ruling system, social system, economic system, and judicial system and so on to the people around the globe. Now the West fears that the return of the religion in its full force will destroy its dominance over the world.
