Not for the first time, the contrast in character between Putin and Obama was illustrated in the latest diplomatic spat over alleged Russian hacking. The temptation to hit back in kind to Washington's sanctions must have been great for Moscow. But in the end, the Russian leader probably showed that the best response was to simply ignore Obama's clumsy stupidity.
With typical histrionics and contrived fanfare, the White House announced that it was expelling 35 Russian diplomats, whom it accused of being "spies" and of alleged hacking during the US presidential election in November. Initially, Moscow appeared ready to reciprocate with an equivalent banning of American officials.
