If Korea ever reunifies, there's going to be a big mess.
Land mines are a military necessity, at least in some situations. Armies find they save the lives of troops, and are useful in defending territory.
These uses, however, have only a time limited utility. And some forms of land-mines we should be able to agree to ban. If there are such things as land-mines that look like toys, and I'm told there are, these things are an abomination. They are directed at children, and civilian children at that. We ought to be able to ban them in the same way that we have banned dum-dum rounds. There ought to be some way of keeping track of where the mines are laid, so that they can be taken up or detonated later when hostilities are over. They should not be the gift that keeps on giving.
It seems it might be well worth working out some sort of agreement that takes at least some of these factors into account. How badly do we hate the English, for example, whom we distrusted and disliked quite seriously through the civil war and for some time afterwards? What would it do to our relations today if there were still English mines blowing folks up on American soil at unpredictable times and places?
It wouldn't improve my feelings any.
