LONDON — “The world is too much with us,” lamented Wordsworth well over a century ago. He had in mind too much “getting and spending,” of which we could use a bit more of these days. Workers would be happier getting a bit more, and businesses would cheer at additional spending.

But in a different sense, the world is indeed too much with us. Iran proceeds with the development of nuclear weapons, no matter how many olive branches and outstretched hands President Obama offers.
