If you believe that Iran missing US troops was either luck or bad aim then I have a bridge to sell you
The point is that with radicals you never know.
The only conspiracy theory which could work is that the US secretly negotiated with Iran that they will let them attack a US base in order to go on with life and the US took precautions to make sure no lives are at risk and from the US side there is no need to respond militarily since no US lives were harmed and tensions calm down and life goes on.
But if this is not true, then Iran was just very lucky here. I mean even as careful as they try to be they should have thought that there is 1 percent chance that an American WILL somehow be in harms way and that would be the beginning of their end.
Hence my question. What were they thinking....
