LEBANON, NIGERIA, HAVE RELIGIOUS, NOT POLITICAL PROBLEMS

Sunni Islam does not mix with Shia Islam.
Shia Islam does not mix with Christianity.
Sunni Islam does mix with Christianity.

In Afghanistan, Taliban – Sunni Islamists – cannot coexist with Mujahideens – Sunni Islamists.
Islamists want to control Islamists and you expect Islamists to coexist with non-Islamists?

When the Islamist population is significant in a country,
Islamists want Sharia law and total control of the economy and government.
The Islamist population in Lebanon and Nigeria are matched by the Christian population.

When Islamists are matched by other Religions as
When oil mixes with water, there is repulsion and revulsion.
When Islamists mix with other Religions, Islamists foment violence and terrorism in a power-grabbing move.

Oil – Islamists – always settle at the top through
Violence and terrorism, as oil always settles at the top of an oil-water mixture without soap.
It is the Islamist way or no way, as there is no Religious soap to facilitate a religious emulsion. 

Lebanon is a smorgasbord of Sunni Islam, Shia Islam, Christianity, and others.
Nigeria is a smorgasbord of Sunni Islam, Christianity, Shia Islam, Fulanis, and others.
If religious oil cannot mix with religious water, do you expect Islamists to mix with non-Islamists?

Lebanon and Nigeria shall always be embroiled in turmoil unless there are new states formed along religious lines to keep religious oil separate from religious water.
