Today’s youth are growing up in the shadow of three bombs — any one of which could go off at any time and set in motion a truly nonlinear, radical change in the trajectory of their lives.

The first, of course, is still the nuclear threat, which, for my generation, basically came from just one seemingly rational enemy, the Soviet Union, with which we shared a doctrine of mutual assured destruction. Today, the nuclear threat can be delivered by all kinds of states or terrorists, including suicidal jihadists for whom mutual assured destruction is a delight, not a deterrent.

But there are now two other bombs our children have hanging over them: the debt bomb and the climate bomb…

That is why I was heartened to see the liberal Center for American Progress stating last week that, while the stimulus is vital to rescuing our economy, the size of projected budget deficits demand that we also start thinking about broad-based tax increases and reductions in some spending and entitlement programs supported by liberals. I am equally heartened when I see Republicans like Gov. Arnold Schwarzenegger urging his party to start taking climate change seriously.
