When President Obama called for a world free of nuclear weapons in Prague, Czech Republic, this spring, many dismissed this part of his speech as idealistic rhetoric.

But the abolition of nuclear weapons is not an unrealistic fantasy. It is a practical necessity if the American people are to have a secure future. President Obama should use his Nobel speech this week to reaffirm his commitment to this essential and obtainable goal.
