In this edition of The West Block we are in Halifax at the International Security Forum.  Is there a division within the NATO alliance?  Is NATO doing enough for Ukraine when it comes to the threat they face from Russia?  And what about the U.S. does it support this global alliance and where do political leaders there view the U.S. and its role as a global leader?

Guests: Rose Gottemoeller, NATO Deputy Secretary General; Pavlo Krimlin, Ukraine Foreign Minister, Senator Mike Rounds, Republican-South Dakota.
