THE OBAMA LEGACY: Russia escalates spy games after years of U.S. neglect.

In the throes of the 2016 campaign, the FBI found itself with an escalating problem: Russian diplomats, whose travel was supposed to be tracked by the State Department, were going missing.

The diplomats, widely assumed to be intelligence operatives, would eventually turn up in odd places, often in middle-of-nowhere USA. One was found on a beach, nowhere near where he was supposed to be. In one particularly bizarre case, relayed by a U.S. intelligence official, another turned up wandering around in the middle of the desert. Interestingly, both seemed to be lingering where underground fiber optics cables tend to run.

According to another U.S. intelligence official, “They find these guys driving around in circles in Kansas. It’s a pretty aggressive effort.”

It’s a trend that has led intelligence officials to conclude the Kremlin is waging a quiet effort to map the United States’ telecommunications infrastructure, perhaps preparing for an opportunity to disrupt it.

“Half the time they’re never confronted,” the official, who declined to be identified discussing intelligence matters, said of the incidents. “We assume they’re mapping our infrastructure.”

Obama thought he’d be the one to have more flexibility after his reelection, but the Kremlin knew better.
