They know now (about pending attacks), they are remaining silent, and more may yet die.
Why does that have to be if they are "peace-loving" moderate Muslims?
I think the goal of Muslims in the USA is to make the USA in the image of other Islamic republics--by force and wanton destruction of all non-Muslims (aka "infidels")
They're loyalties are greater to Bin Laden than to their country or fellow citizens.
Why on earth do we want them here?
They don't even deny that they think the USA should become an Islamic state, they want that for the world. Then they believe there will be peace because everyone will obey Islamic law or be killed. That's the kind of peace they love.
They don't need to use force, the rate that Westerners are committing self genocide through abortion and choosing self over family vs. the birthrate of the Islamic world will ensure they'll capture dominance soon enough.
You are right!
