Potomac Institute for Policy Studies Senior Fellow Amb. David Smith  weighed in on the US-Russia spy swap on the nationally syndicated Jim Bohannon Show.  For many, the case brings back memories of the Cold War era.  Amb. Smith is a former lead negotiator in US arms talks with the  Soviet Union; he says far from ending with the fall of the USSR, reports of Russian espionage against the United States have increased dramatically in recent years. Click here to listen to Amb.
