Another U.S. military strike inside Syria — this time, shooting down a Syrian bomber — has escalated tensions with Russia, even opening the possibility that Russian anti-aircraft missiles will target U.S. warplanes, reports Gilbert Doctorow.

The Pentagon’s announcement that the U.S. military had shot down a Syrian warplane inside Syrian territory merited only inside-the-paper treatment at The New York Times and The Washington Post on Monday, but it became the featured article on the Russian version of Google News citing a Moscow newspaper reporting a warning from Russia’s Federation Council that “the USA can receive a return blow in Syria.”
