Syria and Yemen: both experiencing the same thing from different sects of Islam

Ethnic cleansing of all Sunni Civilians continues unabated in Syria. (Don't let the cease fire fool you). While in Yemen ethnic cleansing of all Shia civilians is also taking place. So, we are watching more and more civilians die in both these places and I suppose it could go on this way for years into the future.

However, any relatives of the civilians being ethnically cleansed are sure to try for revenge in some way, shape or form upon those who killed their parents or other relatives or friends at some point in the future.

So, in this sense, Syria and Yemen are ongoing Time Bombs of angry people who will seek revenge at some point in some way in the future for their lost loved ones.

In this sense Revenge taking has been and likely will also be never ending because it has been going on for thousands of years already in the middle East and might go on for thousands of years more.

The problem for Europeans is if these revenge scenarios are played out between Shias and Sunnis in Europe as the survivors grow up there once having achieved refugee status and accepted within European nations.
