We cannot pass our guardian angel's bounds, resigned or sullen, he will hear our sighs.

We cannot both preach and administer financial matters.

We cannot solve the problem of terrorism by asserting our will on the world.

We cannot gamble with American lives. I will not gamble with American lives.

We cannot kill or capture our way out of an industrial-strength insurgency.

It is easy to dodge our responsibilities, but we cannot dodge the consequences of dodging our responsibilities.
