Barky Obummer is counting on the good will of our enemies to, you know, follow our example by reducing their weapons stockpiles and not developing or testing new ones. He wants to make nukes obsolete.
So the message this incompetent ass is sending to our enemies is this:
"If any nation wants to attack the United States with chemical, biological, or electromagnetic pulse weapons, it need not fear nuclear retaliation as long as it has no nuclear weapons and abides by the Non Proliferation Treaty. So, as New Yorkers (or Washingtonians, or Atlantans...) are coughing their lungs out from mustard gas or dying in the streets of biological weapons, they will know that their government will not use nuclear weapons to retaliate against their murderers."
