1. The explosion cannot possibly be contained underground, and deadly radiation would spread hundreds of miles downwind.
2. Tens of thousands to a million or more people would likely be killed if this weapon is used.
3. Despite its enormous yield, it is ineffective against bunkers that are deeper than 300 meters underground, a distance reached easily by current tunnelling technology.
4. In attacks against underground stocks of chemical or biological weapons, the explosion is more likely to release the deadly agents above ground than it is to destroy them.

These facts are also shown clearly in the animation I mentioned above. Check it out.

Oh, and tell your Senator to support the Kennedy amendment."
