We--by which I assume you mean the United States--are at war with whatever seems to be most profitable to the powers-that-be at the time, whether that is drugs, Muslims, or our own citizens. There is a very valid concern that such a policy of scaremongering and sly abuse of power could result in Bad Things (tm) if the beast decides that a war on one of us would be a worthwhile expenditure of time.
To pretend otherwise is foolish.
There are people out there that wish us harm, as there always have been. Part of the burden of doing great things is the acceptance of the fact that you'll be targeted by those less capable--and part of the requirement is that you bull ahead and don't let it bother you.
