Small? 10 million Muslims is a "small" population? Granted, I doubt even half of them are serious Muslims. (Muslim in name only) and of the remaining number, only a tenth serious enough to become a "Shaheed". (that's 500,000 potential walking bombs) That leaves 4.5 million willing to support and contribute cash to a group or individuals jihad mission. That to me is a fairly large internal threat. Policable? Lets hope so, because that is how we are dealing with it. If we can only prevent more from flooding in, that would be good. Dealing with terrorism somewhere else in the world is preferable.
"Small? 10 million Muslims is a "small" population?"
There's only - at most - about 3 million Muslims in the United States.
"If we can only prevent more from flooding in, that would be good. "
Ah, but our government not only has no plans to do this, but is going out of its way to bring in more.
As a percentage it is less than 1% of the population. While new immigrants in ghettos may have the isolation required to engage in terrorism, I hold out some hope that at that small a portion of the populace Muslims will be rapidly assimilated and inculcated in American values. If not, at least they will presumably have American neighbors who will rat them out for suspicious activities.
