Analyst John R. Schindler says his recommendation for a new, third-party inquiry into the 2010 Smolensk air crash, which killed 99 people and decapitated the Polish government, upset some people.

Moreover, the notion that Putin's forces would blow up an airliner, without regard for innocent life, is anything but far-fetched. They've already done it. I am referring, of course, to the shootdown of Malaysian Airlines Flight 17 (MH17) over eastern Ukraine, an active warzone at the time, on July 17, 2014, killing all 299 passengers and crew aboard the doomed Boeing 777, he wrote in an op-ed for Observer

Most of them died a horrific death when a missile exploded at the aircraft's nose as it cruised at 33,000 feet. This explosion killed the pilots instantly and led to the rapid break-up of the Boeing, its pieces falling in flames six miles to earth. Wreckage and mangled bodies were scattered over a 20-square-mile area in the war-torn Donetsk region of eastern Ukraine.

Dutch nationals made up two-thirds of the dead, 196 persons, so the Netherlands took the lead in the investigation, which published its findings in October 2015. Based on exhaustive examination of the wreckage and all available information, the Dutch report concluded that the Boeing 777 had been taken down by a surface-to-air missile of Russian origin, specifically the 9K37, called Buk (beech tree in Russian). Termed SA-11 by NATO, this is a self-propelled weapons system that provides air defense coverage to Russian ground forces—which was why a Buk was in eastern Ukraine that fateful day, since Putin’s Kremlin had invaded Donetsk earlier that year.

Dutch wreckage analysis left no doubt that a Russian Buk shot down MH17. Shrapnel which could only have come from that system was found in the wreckage and embedded in the bodies of the pilots, who were shredded when the missile exploded just outside their cockpit. No bona fide aviation experts have dissented from Dutch conclusions regarding what brought the Boeing down—or whose missile it was. Although debate continues about why a Russian air defense unit illegally positioned inside Ukraine's borders brought down a civilian airliner—was it an intentional act or a terrible accident?—that the Russian military was the responsible party is not up for debate in the reality-based community.

For their part, the Kremlin and its propagandists for nearly four years now have played their customary fact-free games of spies and lies, claiming that the gruesome end of MH17 was caused by Ukraine somehow, despite there being zero evidence to back up that assertion. It is an established fact that the missile which killed 299 innocent people was fired by a Russian weapons system located in an area under Russian military occupation that day. No amount of Muscovite disinformation can change that awful reality.

This tragedy is back in the news this week because Dutch investigators have announced that the Russian military's 53rd Air Defense Missile Brigade was the outfit which shot down MH17. Normally based in Kursk, not far from the border with Ukraine, that brigade was known to have deployed subunits in eastern Ukraine in 2014, so this conclusion is no surprise to anyone who watches Kremlin military news closely. Today, the foreign ministers of the Netherlands and Australia upped the ante, issuing a joint statement holding Russia responsible for this atrocity—Australia lost 27 citizens in the crash—and Western countries are already signing on to this conclusion, with Germany taking the lead. Predictably, the Kremlin is pushing back, implying that it is the victim of a nefarious smear campaign, but there is now so much evidence of Moscow's guilt in the public domain that the usual Russian disinformation tricks are no longer working in the West outside the ranks of confirmed Putinphiles.

Open-source intelligence analysts have piled on this week as well, with the amateur sleuths at Bellingcat issuing a detailed report which confirms that the 53rd Air Defense Missile was the unit to blame here, while fingering (with some mainstream media help) a senior Russian military intelligence (GRU) officer named Oleg Ivannikov, codenamed Orion, as a key person of interest in the shootdown. Bellingcat's report includes an impressive amount of detail, some gained from sources in Russia, about Ivannikov's troubling background as a Russian spy specializing in dirty work.

This is well-done open-source intelligence, but there's not really much front-page news here. GRU's involvement in the MH17 shootdown was known almost immediately, while within weeks of the catastrophe, Ukrainian intelligence was releasing signals intelligence (SIGINT) intercepts to the public which left no doubt that the Russian military was behind the shootdown. Moreover, investigative journalists in Germany within a few months of the disaster solidly fingered the 53rd Brigade as the culpable Russian military unit. While it's good news that Western governments are finally holding Moscow to account for this terrible atrocity, there's more than a bit of cheek in proclaiming long-ago reported information as breaking.

Then there's the awkward fact that our Intelligence Community has known the full, terrible story of the MH17 shootdown from practically the moment it happened. Thanks to American acumen in SIGINT and satellite imagery, spies in Washington within mere days of the disaster knew who did it—and how the nightmare unfolded. As reported by The Washington Post only five days after the crash, American intelligence knew that the Kremlin was lying about its innocence in this sordid affair. The Obama White House authorized a limited release of intelligence information, based on "sensors that traced the path of the missile, shrapnel markings on the downed aircraft, voiceprint analysis of separatists claiming credit for the strike, and a flood of photos and other data from social-media sites" as the Post put it, to rebut Kremlin disinformation about the incident.

However, this was a tiny fraction of what our Intelligence Community knew about MH17. As three IC officials have confirmed to me, Washington possessed damning information about the shootdown, including SIGINT which left no doubt that the Russian military—specifically the 53rd Air Defense Missile Brigade—downed the airliner. Detailed, top-secret intelligence from the National Security Agency, which the White House was briefed on within a couple days of the disaster, told the tale. Nevertheless, the Obama administration elected to sit on this bombshell, allowing dishonest Kremlin narratives to gain traction as the public tried to ascertain what exactly had happened to the doomed jetliner.
