Islam is the basic belief in God and Islamic ideologies are interpretations of the Koran and in some cases the Hadiths.
As Islamic peoples reproduce, apparently there are indeed relations in Islam.
Same relation as the relation between Christianity and the western civilization. Or the Vedic dharma and the Hindu civilization. While Islam has spread by invasion, force, and mass production of children and forcing Islam on the children, the Vedic dharma survives and spreads since millenniums by free will. 1000 years of Islamic onslaught could not kill this Vedic dharma.
There is no difference between "two nation ideology" and "ideology of Pakistan".Two nation ideology is based on Islamic concept that Islam is separate relegion and Muslim has there on identity and style of living means Ideology of Pakistan is based on it and say that Muslim and Hindu of hindustan(present India ,Pakistan and bangledesh ...) are two different nations.
Islamic Economy: The term used to refer to Islamic commercial jurisprudence and also to an ideology of economics based on the teachings of Islam that takes a middle ground between the systems of Marxism and capitalism. Islamic commercial jurisprudence entails the rules of transacting finance or other economic activity in a Sharia and Sunnah manner.

A legal divorce is one according to the laws of the country where you live. An Islamic divorce is one that is according to the laws of Islam and is the same through out the world. Only the Islamic divorce is accepted in Islam.
Islam is a religion that can be represented by Islamic Community, Islamic state, Islamic nation, or Islamic world.
First Jamat-i-islam is not an Islamic group but a political party. Government and many political parties expect them to be connected with international terrorist groups. Its mainly for political gain. But there are many of their deeds that were terrorist acts.
Between the two types of the Islamic religion it was the Sunni.
If you mean, where Islam is not practised in toto, in letter and spirit, then most of the Islamic countries are not following Islam.
Islam
Our society is certainly not a Islamic society because as most our people are revisionist (in between Islam and modernism) and due to this the modernism is there.
