Donald Trump and Vladimir Putin could destroy each other

Supporting the US president may yet backfire on the Kremlin

If Vladimir Putin did help to put Donald Trump in the White House, it would be the ultimate intelligence coup. Yet, it might also prove to be the ultimate own goal. An operation designed to ease the pressure on Mr Putin’s government by installing a friendly face in the White House has instead led to a tightening of sanctions on Russia, and a dangerous increase in the domestic political pressure on the Russian president.
