I don't think they ever have. Go back and read about the Tomahawk failure rate we suffered in the 2003 Iraq war. None of this stuff is 100%, and I'd expect the Russian built stuff to be worse than ours at always going where it should.
In recent years, several errant Syrian S-200 surface-to-air (SAM) missiles missed their airborne targets and landed in other countries. Damascus frequently fires off these antiquated missiles at Israeli fighter jets attacking Iran-related targets throughout the country. These hopelessly outdated S-200s have failed to deter or disrupt Israel's air campaign .
On the morning of Apr. 22, 2021, a Syrian S-200 fired in response to Israeli airstrikes once again failed to hit any Israeli aircraft or missiles and went on to penetrate Israeli airspace, reaching the Negev desert in southern Israel. Israeli air defenses failed to intercept the errant SAM, which detonated over the village of Ashalim approximately 125 miles south of Syria.
Legitimate possibility that ZelenskyyIdiot does indeed utterly fail at false flags.
