I was in EU for both the Paris bombings and a recent week long Lufthansa strike. The chances of something actually happening to you are slim to none, that said if you're on a tight timeline and there's a travel lockdown getting back to the US on schedule may be problematic. If you're flexible though don't see any reason not to go. If it makes the wife feel any better I noticed a definite increase in security both while traveling around and definitely at airports, so from every indication I saw you're safer going now than you would have been a month ago.
