“Good morning American pilots, we are here to greet you on your Fourth of July Independence Day,” a Russian Tu-95 Bear bomber crew member stated over the emergency aircraft channel. 

Meanwhile, Russia’s across-the-board buildup of nuclear forces and revised doctrine are increasing the danger of a nuclear war, according to a think tank report on nuclear threats.

Defense officials and the Colorado-based U.S. Northern Command said this week that two U.S. F-15 jets intercepted the Russian bombers on July 4 as they flew as close as 39 miles from the coast of Mendocino County, north of San Francisco.

During the intercept, a crew member on one of the bombers issued a warning in a radio message, according to defense officials familiar with the incident this week.
