I imagine I would find it somewhat more difficult to justify having the most heavily locked door in the world - which, by reasonable context, is closer to analogy being drawn above.
In your analogy, it's clear to me that the US is better suited for that status than any of the other realistic candidates.
My point was not that no-one could justify an extreme of door locks but that I could not. If someone wants to try and justify an extreme of door locks, they're welcome to do so. But merely noting that we all do some thing, or that someone has to have done the most of it, is not such a justification even by analogy.

1. That Petersellers has grown to adulthood with a remarkably naive understanding of human nature.
2. Believes that the industrial and design capacities of modern nations are such that we could conjure effective weapons faster than a strike could be effectively delivered.
3. That they meant their statement in a somewhat more bound form.
Since 1 & 2 seem either unlikely to be held, or to be held by a mind that hasn't been convinced by the other arguments / observations it would have come across to the contrary, the latter seems the most useful context to interpret their remarks in. The others would either be mistaken assumptions or remove the point of talking to them.
