“You know, the media and the politicians would have us believe that there's something inherently immoral about terrorism. That is, they would have us believe that it's not immoral for us to destroy a pharmaceutical factory in Sudan with cruise missiles, but it is immoral for someone like Bin Laden to blow up a government building in Washington with a truck bomb. It's okay for us to take out an air-raid shelter full of women and children in Baghdad with a smart bomb, but it's cowardly and immoral for an Iraqi or Iranian agent to pop a vial of sarin in a New York subway tunnel. Really, what should we expect? They don't have aircraft carriers and cruise missiles and stealth bombers. So should we expect them to just sit there and take their punishment when we wage war on them? I think that it is the most reasonable thing in the world for them to hit back at us in the only way they can. It actually takes more courage to be a terrorist behind enemy lines than it does to push the firing button for a cruise missile a hundred miles away from your target. And yet we certainly will see Bill Clinton and every other Jew-serving politician in our government on television denouncing as a "cowardly act" the first terrorist bomb which goes off in the United States as a result of a war against Iraq. And don't be surprised when the FBI and the CIA announce that they have studied the evidence carefully and have determined that it was Iranian terrorists who built the bomb, so that the Jews will have an excuse for expanding the war to take out Iran as well as Iraq.”

if you use less force, you kill off more of humanity in the long run, because you are merely protracting the struggle.

Context: I believe that homosexual acts between individuals are immoral, and that we should not condone immoral acts. I do not believe that the armed forces are well served by saying through our policies that it's okay to be immoral in any way, not just with regards to homosexual acts.

That's not accurate. Although it's true they were used as shields, the fact is they were humans already. So if these humans were used as shields, they were human shields. They weren't being used as human shields. Got that?

Variant: I must affirm that it is just as wrong, or perhaps even more so, to use moral means to preserve immoral ends.
Context: I have consistently preached that nonviolence demands that the means we use must be as pure as the ends we seek. I have tried to make clear that it is wrong to use immoral means to attain moral ends. But now I must affirm that it is just as wrong, or perhaps even more so, to use moral means to preserve immoral ends.
