Kaine Urges Sanctions, Rejects Iran War Path

Sen. Tim Kaine tells CBS's Face the Nation that the U.S. should not pursue military action against Iran, advocating sanctions and diplomatic pressure instead; he cites Syria's Caesar sanctions as effective, supports counter-ISIS actions but not actions against the Assad regime, calls for a public bipartisan debate on Venezuela policy, and warns that threatening Denmark/Greenland could isolate the U.S. and damage NATO.
