"Imminent threat"? Where have we heard that before?

Except, this time it's from John Kerry:

We will use superior military force to overcome any enemy. Let me be clear: like you, I defended this country as a young man. And I will defend it as president. I will never hesitate to use force when it is required. Any attack will be met with a swift and certain response. Any imminent threat to our security will be dealt with swiftly and severely. I will never give any nation or international institution a veto over our national security. And I will build a stronger American military.
