Pacifism as a religious doctrine is non-existant in mormonism. That is not to say we don't prefer peace, we abhor warfare, but the occaisional need for war to establish a just peace is well recognized as is the need for soldiers to man the ramparts in times of peace. A great deal of the book of mormon is taken up by stories of the ongoing hot and cold wars between the Nephites and the Lamanites. Several of the heroes of the Book of Mormon were commanding officers in the Nephite armies.
Mormons noted for thier military service include Capt Mervyn Bennion USN, mortally wounded at the battle of Pearl Harbor, he was posthumously awarded the Congressional Medal of Honor for saving his ship, the USS West Virginia and became the first mormon to have a US Navy warship named after him. General Robert C. Oaks, formerly the commander of US Air Forces in Europe currently serves in the Quorum of the Seventy. Robert D. Hales, a former USAF fighter pilot serves on the churches Quorum of the Twelve. As does Richard G. Scott, a nuclear engineer and former member of Admiral Hyman G. Rickover's staff (a position wich would require a saint if ever there was one

). Lt. General Bruce Carlson, C.O. of the United States 8th Air Force is also LDS.
Last, but by no means least, is my father; Lt. Paul Hinman. Formerly of the 14th Canadian Hussars Armoured Regiment.
The general sense I get from the membership of the church is that they are very supportive of the war on terror. Utah is an unbreakable republican stronghold, politically speaking. Like many christian sects, the LDS church is very pro-Israel and the threat against both us here in North America and Israel by extremist islam is of great concern to us. The "let Israel die" attitude expressed by even those twoofers not overtly anti-semitic runs contrary to the basic feelings held by the vast majority of mormons. Like the general public as a whole, 9-11 twoofiness just isn't registering with the members of the church. But those who are aware of it regard it as absurd and nonsensical. There is a small handful of LDS whom I have shown
your research on the links Jones has developed with the neo-nazi movement and they have all been disgusted with Jones's new friends (free plug there for ya, Brainy

).
Here's a sampling of Mormon thought on the Jones affair that represents the mainstream of the church:
An embarrasment... good riddance"
Pandering to paranoia for popularity.
Well those of you calling for BYU to do something about Steve Jones will be happy.
EDIT: Regarding Steve Benson, he left the church many years ago and became one of it's most voiciferous critics. He's since become a sterotypical member of the liberal media. Steve Bensons pacifism is Steven Bensons.
