It isn't about the ultimate odds, it is about the change in odds. I'm no more likely to slip and break my next in Oman than I am in my backyard. Driving is certainly one thing than can be more dangerous abroad, but if you click through the links I provided you will see it mentioned. Those sites are resources on much more than terrorism.

The reason I only copied highlights from the terrorism sections is because the original comment was regarding the targeting of Americans due to current political climates. I don't think the indigenous poisonous flora and fauna are targeting Americans for their politics.
