DEAR EDITOR:

We must do more to strengthen our power grid against an electromagnetic pulse (EMP) event.

Such an event can result from an attack by terrorists or by another country 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 internet at the least in an anti-satellite attack.
