I suspect it may be a way to plant the seed of fear while appearing patriotic, but then I am suspicious of all sources these days. I've seen a number of articles from various places that are suddenly emphasizing community vulnerability due to the use of Guard/Reserve components, and I believe there is a coordinated effort by the media to set this up for use against action in Iraq when the time is ripe. Bad as things may get, they will make the action seem worse than it is, and we all know why.
This family has a dog in the upcoming fight, and while it is nice that someone at the WPCo. expresses these sentiments, it would also be nice if they would maintain a pro-soldier attitude the rest of the time. The deaths of these four servicemen should be remembered, and their sacrifices honored, with no political agenda. There is more to this piece than a memorial for four fallen men, and it bothers me a bit; again, I may be hypersensitive (or some may say insensitive). If this piece passes your (an editorial "your," BTW) personal litmus test, then accept it in the spirit you wish, but I am skeptical of the source and the motive.
I do, however, agree that these four men and their families are deserving of as many prayers - and as much reflection - as anyone who dies in the line of duty. That their importance may seem to be predicated on news cycles says much about us, not about them.
