In wartime, which is what we are in today, we don't allow forests to conceal our enemies' heavy weapons, we burn down or defoliate the forest. That's war.
How nice. You're talking about millions of American citizens. How are you going to "defoliate" that "forest"? Are you going to force them all to convert to Christianity by law? But even then, you probably won't trust their sincerity. I guess you'll have to kill them.
And even then, the terrorists will be able to blend into the Arab American communities. That's a forest, too. Now you are talking about something like 10 million American citizens. Are you going to kill them, or just put them in concentration camps? And since most Arab Americans are of mixed race, how will you decide who's a tree and who's merely a bit of undergrowth? Are you going to use the "one drop" rule?
I submit that your mindset is a greater threat to America BY FAR than terrorism. The terrorists just want to destroy our lives. You want to destroy our freedom.
So I say, monitor those you suspect closely, expel non-citizens who even give the slightest reason for suspicion, and arrest and assassinate operatives worldwide.
In the long run though, we must stand on guard against the Islamic tide. That's a given. Look at Europe. They can't sneeze without offending their Muslim communities.
If there are no more 9-11 level events, nothing like what YOU said will come to pass.
If more 9-11 level attacks occur, and the terrorists' tracks AGAIN lead directly through the mosques, cultural centers and islamic foundations, THEN we will certainly consider the internment or deportation of all arab moslem NON CITIZENS. To do less would be to commit national suicide, elevating PC over survival.
If a "hyper 9-11 event" occurs, such as a suitcase nuke going off in an American city, and AGAIN the trail leads directly through the "moderate islamic community", then far more draconian methods will be used. I don't advocate this, I am trying to make you aware of the "facts of life" of national survival.
