WASHINGTON (MarketWatch) -- The U.S. is examining economic and diplomatic steps to "isolate" Russia if it continues to intervene in Ukraine, President Barack Obama said Monday. Russia is in violation of international law, Obama said at the beginning of a meeting with Israeli Prime Minister Benjamin Netanyahu. Obama said Russia is on the "wrong side of history" and Ukrainians must "control their own destiny." Obama did not specify what steps the U.S. could take.
