No, LH, tactical nukes are intended to be used certain battlefield situations -- say, for instance, that a whole bunch of bad guys are on top of a mountain that you want to take, and you have to take it fast to maintain the momentum of the attack. Just throwing people against it will slow the attack, and bombing it conventionally will take forever AND destroy the shock of surprise. So you nuke it and either capture it with the PBI while the defenders are still wandering around wondering what happened or write it off 'cause it's now a heap of hot slag (several meanings of "hot").

As for collateral damage -- civilians have always died in war. Rocks, metal, gases, blast, fire don't care if they affect soldiers or civilians. You drop a bomb or fire a shell or a rifle, someone or something is going to catch the result -- could be good ol' Mamma Earth, could be an inoffensive tree, could be a bad guy, could be a child playing in their room.

Ronny Reagan was a staunch advocate of "trickle-down economics" and he and his CERTAINLY did not use it satirically. See where it's brought us?
