That ship has long since sailed, however, and now there are more stateless groups than ever, carrying out more pseudo-wars than ever. It is of particular interest to me that Islam is the only religion in whose name these particular types of situations exist, no other religion has produced extremists that are capable of creating and sustaining actual war efforts in the complete absence of a recognized state.
This shouldn’t be too surprising to you.
The majority of these militant groups emanate from nations that are for all intents and purposes - failed states.
The Russians seem to think that the only way to govern places like Afghanistan, Iraq, and Syria is through the “Strong-Man” model of government - but of course Putin would encourage that model given his own history. But they do so in the belief that it would be the only way to repress all of these militant groups.
Of course the rest of the world is more than willing to help in doing this. But if we are collectively unable to bring this under control, if it continues to get worse and not better, it actually does mean that the concept of Islam as a religion of peace and tolerance loses credibility and ceases to be as true as most Muslims would like it to be.
There is a host of issues implicit in what your saying - the largest one being if a person who happens to be Muslim identifies themselves as a member of the political polity which they reside in.
This is where I should congratulate the Americans - as they lead the way in terms of integration of foreigners with differing cultural/ethnic/social/religious backgrounds… hence the reason why they as a Western nation are a much smaller contributor of people joining the ranks of the groups like ISIS.
Contrast this with the Europeans…and the Russians…
One of the primary issues happens to be what level of integration has occurred between the immigrant population and the their host country.
France is notorious for having these issues in terms of the the migrant population that are Muslim even BEFORE this current wave of refugees.
You can find 3rd generation Tunisians/Algerians/Moroccans, et al. who while having been born and raised in France with French as their primary language STILL feel shut out of the society which they supposedly belong to.
So if they can’t identify with the people around them, may draw their sense of Self from another type of community…
…and this is where the problems arise given the options presented to them.
