No nation can claim rights without acknowledging the duties that go with the rights. It is a contemptible thing for a great nation to render itself impotent in international action, whether because of cowardice or sloth, or sheer inability or unwillingness to look into the future.

Context

“From Professor Simkhovitch's book we Americans should learn: First, to discard crude thinking; second, to realize that the orthodox or so-called scientific or purely economic or materialistic socialism of the type preached by Marx is an exploded theory; and, third, that many of the men who call themselves Socialists to-day are in reality merely radical social reformers, with whom on many points good citizens can and ought to work in hearty general agreement, and whom in many practical matters of government good citizens well afford to follow.
CHAPTER XIV THE MONROE DOCTRINE AND THE PANAMA CANAL
No nation can claim rights without acknowledging the duties that go with the rights. It is a contemptible thing for a great nation to render itself impotent in international action, whether because of cowardice or sloth, or sheer inability or unwillingness to look into the future. It is a very wicked thing for a nation to do wrong to others. But the most contemptible and most wicked course of conduct is for a nation to use offensive language or be guilty of offensive actions toward other people and yet fail to hold its own if the other nation retaliates; and it is almost as bad to undertake responsibilities and then not fulfil them.” source
