The leaders of the congressional intelligence committees say that the United States is not safer today than in recent years.

Sen. Dianne Feinstein (D-Calif.), chairwoman of the Senate Intelligence Committee, and Rep. Mike Rogers (R-Mich.), chairman of the House Intelligence Committee, said in an interview aired Sunday on CNN’s State of the Union that terrorism is up worldwide and the United States needs to be vigilant to combat the growing threats.

CNN’s Candy Crowley kicked off her sit-down interview, asking, “Are we safer now than we were a year ago, two years ago?”

“I don’t think so,” Feinstein replied. “I think terror is up worldwide, the statistics indicate that. The fatalities are way up. The numbers are way up.” Rogers concurred. “I absolutely agree that we’re not safer today … the pressure on our intelligence services to get it right to prevent an attack are enormous. And it’s getting more difficult.”

The recent uptick in terrorism reminds us of the need to remain vigilant. But it is also important to keep in mind long term trends.

According to Pinker, there has been a sustained downward trend in deaths from terrorism.
