Letter to the editor: U.S. must do more to strengthen power grid against attack

To the editor: We must do more to strengthen our power grid against an electromagnetic pulse event. Such an event can result from an attack by terrorists or by another country (e.g. China may already have the capability, which it may use in an economic crisis) or it can occur naturally.

It could result in devastating loss of life. There is disagreement on this, but why take chances?

We should also have a ground-based GPS backup system (like Russia has), or we could lose the internet - at least - in an anti-satellite attack.
