Even if they were empty buildings which they were not show me a country that would dare to hit american basis directly from its soil and announce it publicly ...
It is even hard for them to criticize america let alone to hit them:
no injury or death is just an american joke ,
Taji was attacked by 15 rockets 3 were killed & 12 injuries and you're telling me 13 BM didn't kill anyone? the point is they knew they were about to get attacked so were ready.
Those empty buildings were in fact the site that operate american drone operations:
"U.S. officials won't say if the drone strike that killed Soleimani was launched from this base. But the area from where U.S. troops launch drones suffered some of the worst damage in last week's strike."
And Iran razed them to the ground by its pin point missile technology:
The outcome of this operation so far has been pushing american to leave many Iraqi bases and concentrate in Al assad which shows its importance. while POTUS promised us targeting 52 cultural sites ..
On the other hand as we witnessed Iran shot downed american 250 million $ drone .. nothing in return.
They tried to seize our tanker .. we seized their tanker next day .. nothing in return.
We sent our tankers with online tracking and Iranian flag next to their borders .. nothing happen.
Their patriots and other ADs have been humiliated in attack against KSA oil facilities dropping 5 million productions.
So I can assure you even if entire american soil get burned down to its ashes which I doubt it they won't attack us as they know we would respond.
