Believe what you want.
USA and allies say that Russian cruise missiles crashed in Iran citing secret sources
Non Western press and Russia deny it and Iran says it does not find any relicts (it could be false as they are Russia friends).
US is a year that hits IS and there had been IS casualties but no panick. Russia hits IS and others (u to chose if you can find a good terrorist…the US found the hard way as their US trained rebels defected immediately) and Turkey is alarmed as already 3000 terrorist fled Syria.
The fog of war.
