On February 22, popular protests led to the fall of the pro-Russian government of Viktor Yanukovych in Kiev. On February 27, in response to this setback, President Vladimir Putin sent forces into Crimea to seize it from Ukraine. On March 19, President Barack Obama delivered his response. He reassured Putin, “We are not going to be getting into a military excursion in Ukraine.” Obama added, “What we are going to do is mobilize all of our diplomatic resources to make sure that we’ve got a strong international coalition that sends a clear message.”

The message is clear. The problem is its content. Obama certainly isn’t sending the message that Colin Powell, after the Cold War, wanted America to send: “Superpower lives here.” Obama’s message, by contrast, is: “Superpower once lived here. No forwarding address.”
