.0001% less chance of nuclear winter

Note: my link for this has expired. Here's an alternate that still works, but it references the same dead link I had. In the meantime, here a quote from the original source:

"Thus, if the Minuteman III ICBMs have to be used in some future nuclear war, their rocket motors will not pollute the atmosphere. EPA regulations do not apply in foreign countries, so no changes are being made to reduce the harmful environmental effects of the nuclear warheads"

That's right folks, Uncle Sam's ICBM arsenal is now more environmentally friendly because their propulsion has been reworked in order to meet EPA regulations.

Update: The 'dead' link works again.
