And it doesn't take very many of them, either, in an age where technology offers a huge destructive force to relatively few.
There is an underlying pacifist assumption that only conquerors and would-be conquerors possess swords, and that universal disarmament will result in a rejection of force as a policy tool. That is a lesson people must un-learn as often as the "war is a first resort" lesson.
This is exactly what scares me the most. We in the West (and I think we can include large parts of Asia too) perfectly understand the benefits of peace.
But there were, there are now and probably always will be ruthless people who get instant advantage acting uncivilized way inside of the pacifist crowd. When such ruthless people are not just opportunist who can be bought off (at least in theory) but adherents of an irreconcilable religious fanaticism; and when technological advances allow small numbers of people to create chaos in the society that only huge armies of the past were capable of doing; all this in the open and accessible world -- it is scary. Especially so that large part of the population (half here and most abroad) deny that such threat exists at all.
The only solution is (like VDH and others noted) is for adults to quietly do their business and try to educate "teenagers" if it all possible.
And when we have a democratic party conniving with the Leftist, lying, despicable MSM to defeat the US at every turn, who secretly pray for another hideous Islamofascist attack with great loss of life in the US, it's beyond belief. We're at war, and they can't see beyond the end of their nose, pointed straight at the White House.
