So we had to get rid of it ...
The answer of how to deal with the threat of "home-grown" Jihadists and their support network is difficult. I would be careful abut casting this as an "us versus them" conflict in which our innate goodness or wisdom shows us the way and justifies how "we" decide to deal with an major part of the world's population following a particular religion. And in which all of "them" are the same.
I believe we have an obligation to actively resist evil and we need a lot more of this resistance. But I'm going to rely on God's wisdom and plan for dealing with all those non-jihadists following the misguided path of Islam. I'm also going to remember that "Vengeance belongs to the Lord" and not us - it is much better that way.
The great majority of muslims are amenable to reason and love. I heard a presentation by a missionary couple who had worked at a Christian hospital in one of the emirate countries.They were allowed to openly call their hospital a Christian Evangelism facility and to openly worship as Christians in a muslim country. Why? Because they had been giving medical care to the people of the country for many decades. The leader of the emirate had been born in that hospital. Have you ever heard this story on the news? Of course not. Please, please, please remember that we only hear the negative side of things on the news and in the media. Do not let this negativity color your opinions.
