I stand by my statement. With no security, people are (or should be) more vigilant, considering the stakes. With a false sense of security, people tend to sit back and think "It couldn't happen again." And, as Israel has shown us with a contiguous border a heck of a lot shorter than ours, it can, again and again.
"Fortress America" doesn't work. But then again, neither is our current laissez-faire approach to securing the border good enough for me.
Me neither yet there is a plan (nothing to do with Kerry). If a nuke goes off here, our troops will be called back immediately, any 'friends' in Iran will be notified to leave as well, the rest will be left to history.
