On the eve of the 13th anniversary of 9/11, almost half of Americans feel less safe than they did before the attacks, a new NBC News/Wall Street Journal poll finds.

According to the poll conducted Sept. 3-7, 47 percent of 1,000 registered voters surveyed said the country is less safe than before the Sept. 11, 2001, terrorist attacks on the World Trade Center and Pentagon. That’s more than twice the level of fear among Americans a year after the attacks, when 20 percent said the country was less safe, and an increase of 19 percentage points from last year.
