Hillary: Be very afraid

Hillary has decided that national security and fear are the new message that will resonate for her campaign. On one hand, it's nice to see a Democrat finally embrace national security, and even fear, and turn it to our advantage. On the other hand, she's using it against fellow Democrats. Then again, isn't it a fair point to ask whether Hillary and/or her competitors are ready to handle the job on day one? I suspect all of them are, but am curious what you think? Fair game, or foul?
