It will shock many - I've lived a full life and really enjoyed my time as a pop star.
But I really believe it is in America's interest as well as that of the free world more generally to stop Iran from getting its hands on nuclear weapons. This regime has threatened to wipe Israel off the map and bring about a world without America, and either of those is a really bad prospect.
I don't know if people feel this way, but I think by nature that when you start off as a young pop singer, they assume that you're a bit pampered, prissy, and precious, or that you live in a bubble and not in the real world. For me that's not the case.
