We have already written about escalation in Syria post the shooting down of a Syrian Aircraft by US Forces here and why this is a big deal.
More evidence support this now follows:
Late on Monday the 19th, was reported by Russia’s Sputnik: “In areas where Russian aviation is conducting combat missions in the Syrian skies, any flying ojects, including jets and unmanned aerial vehicles of the international coalition discovered west of the Euphrates River, will be followed by Russian air and ground defenses as air targets” — meaning ordered out, or else immediately shot down.
In international law, and as recognized by the U.N., Syria has been invaded by the United States, was never invited into the country but is instead there as an invader. Russia was invited in; Iran was invited in; but the U.S. are only invaders. And, now, Russia and Syria will start treating the U.S. as such.
When U.S. Presidential candidate Hillary Clinton repeatedly called for the U.S. government to establish a no-fly zone in Syria, she was proposing that the U.S. invasion of Syria become recognized officially by the U.S. government, and this would have meant immediate war by the U.S. against Syria, Russia, and Iran, in the battlefields of Syria. President Barack Obama had decided not to go that far — to war against Russia — but Hillary Clinton insisted on it. And now, Russia has actually done it — but (unlike if the U.S. had done it) legally, in defense of the sovereign government of Syria, not as an invader. (Furthermore, most Syrians support that government, and 82% of Syrians blame the U.S. for the invasion of Al Qaeda and other jihadist forces to overthrow it — most of which are foreigners — into Syrian territory.)
If the U.S. fails to apologize and to find some way to save face, but instead persists in its invasion, even after this warning, then either the U.S. or Russia will win that traditional war in Syria
