Even Trump isn't stupid enough to spend $16 million (the cost of the MOAB) to destroy some tunnels in Afghanistan.  Oh, and kill precisely 36 terrorists and no civilians killed.  All tallied and wrapped up for media consumption  moments after the bomb hit - no need for investigation!    

You think terrorists can't get hold of bulldozers?  How do you think the tunnels were built in the first place?  

Think harder  
And it's at this point that the "fake news" mantra actually might be useful.
