President Vladimir Putin said Tuesday, June 4, 2013 that Russia hasn’t yet fulfilled a contract to send sophisticated S-300 air defense missile systems to Syria to avoid tilting the balance of power in the region. Russian officials have acknowledged that Moscow signed a deal for the delivery of the powerful missiles a few years ago, but have been coy about whether any of them have been delivered.
