It is being reported that Tehran communication did alert the USA of attacks before time of missile launch. There is a source from journalists in Iran confirming that a decrypted message was sent to warn of Iranian attacks on Iraq.
This is being repeated a lot by Middle East journalists: “Tehran told Washington DC through proxies that it will bomb US bases in Iraq to save face and claim it is a response for killing Soleimani. That’s why the USA emptied its bases hours before the attacks. Zero casualties.” The above is a translation of what Middle Eastern journalists are saying Vs MSM in America.
The message was sent via proxies which was decrypted on time before Iran launched missiles.
So far no casualties have been reported of Americans as they evacuated their people from bases that housed American military before time of missiles were launched.
