As we anxiously watch the news, worrying about our friends, family and everyone else we don't directly know - we must remember that there is a greater power watching out for every one of us. Sometimes it's hard to remember G-d, since we are used to believing that we hold our fate in our own hands - but we must.
There is a push on Facebook to make this Shabbat, Friday, November 23, 2012, a "Worldwide Shabbat Observance for protection of Israeli military and civilians" - and I think it's a great idea. As the FB page mentions - Shabbat is a source of blessing. We certainly need G-d's blessing now.
