Lets look at the fundamental issues at the base layer.
National security is the survival of the nation state (the people, the laws, the societal system, and the culture) from internal and external
In the US and the UK you have a separation of church and state. That is to say that religion cannot affect the people, the laws, the societal system,
and the culture without the people's express voluntary action. Islam explicitly demands the fusion of church and state through it's various tenets,
but also explicitly through sharia. This ideology from the most fundamental of base layers therefore constitutes a well defined and categorical
threat to national security for countries that require a separation of church and state as part of their national identity. It really is that simple.
However, Islam is unique in that it not only dictates a moral, cultural, and societal system, but a political and legal system as well. It is quite
literally a complete system. The religion demands its followers to ignore the law of the land if it isn't Islam. If that is not a direct threat to
the national security of a country that separates church and state, then I don't know what is.
I find most religious ideology abhorrent, savage, and backwards. I take individuals for who they are, and my Muslim friends would probably hate to
hear me say this, even though most of them are only sporadic practitioners. It is, however true.
People can ignore it as much as they like, but that's the basis of the situation. When Muslim populations in non-Muslim countries reach a certain
percentage, then that country, regardless of how successful its original system was for its people, turns Muslim. People don't like to mention it or
are ignorant of it, but that's one of the many reasons for the Yugoslavian civil war that wracked the Balkans throughout the duration of the 1990s.
