Respectfully, "tactical nukes are better" is probably not a literal reference by Q, and he is not saying a tactical nuke is to be deployed as part of the plan.  Probably, it's  indicating or characterizing the type/kind of strength of the upcoming boom.  Since he has recently posted about U1, and uranium does play a role in nuclear weapons once enriched, perhaps the phraseology is specifically intended, versus any other kind of big boom he could have phrased it as.  Agreed the stuff that leaves the ground is not particularly dangerous, and neither are carbon, sulfer and potassium nitrate until mixed the right way to make gunpowder :)
