Musket,
the first thing they would realise is that it is not unequivocal.

Yes it is.
Look up what the real scholars say about it, and then tell us why we should ignore the experts and listen to you.

Jim, British policy on arms sales is highly restrictive. See what Amnesty says.
British policy on arms sales has nothing to do with faith, church or commandment. It is purely political and rational, which is how you atheists want government policy to be.
This discussion is about religion.

Dave and Greg, I acknowledged early on that some Christians, including Quakers, are pacifists. We have discussed conscientious objectors years ago.

They are a tiny minority. The main churches do not and never held that it is always wrong to take life in any circumstances.
Christians go out lethally armed as police or military and always have, knowing they are breaking no commandment unless they murder.

Christians have to consider such things, and they do.
