The rise of Donald Trump has been accompanied by predictable murmurs 
of “only in America”. But the Trump phenomenon is better understood as 
part of a global trend: the return of the “strongman” leader in 
international politics.

Rather than leading the way, America has arrived late
 at this dispiriting party. Historians might one day highlight the year 
2012 as the turning point. In May of that year Vladimir Putin returned 
to the Kremlin as president of Russia. A few months later Xi Jinping was
 installed as general secretary of the Chinese Communist party.
Both
 Mr Putin and Mr Xi replaced uncharismatic leaders — Dmitry Medvedev and
 Hu Jintao — and moved swiftly to establish a new style of leadership. 
Compliant media were encouraged to build up a cult of personality, 
emphasising the strength and patriotism of the new man at the top.
The
 trend that began in Russia and China quickly became visible in other 
countries. In July 2013 there was a coup in Egypt, which resulted in the
 overthrow of the Muslim Brotherhood and the emergence of Abdel Fattah 
al-Sisi, the former army chief, as the country’s new strongman leader. 
The following year Recep Tayyip Erdogan, who had already served 11 years
 as prime minister, was elected president of Turkey. 
He immediately moved to strengthen the presidency, marginalized other leading politicians and cracked down on the media.
The
 Erdogan phenomenon demonstrates that democracies are not immune to the 
lure of the strongman. Mr Erdogan is an instinctive authoritarian but he
 won power through elections. Narendra Modi, who was elected prime 
minister of India in 2014, ran a campaign based around his own strength 
and dynamism, promising to reverse years of drift under the 
mild-mannered leadership of Manmohan Singh. In Hungary, Viktor Orban, an
 elected prime minister, has demonstrated strong authoritarian 
tendencies. 
This global trend is gathering pace. Last 
week, the Philippines elected as president a populist wild man, Rodrigo 
Duterte — widely known as Duterte Harry — replacing the cautious 
technocratic, Benigno Aquino.
And then there is Mr Trump. 
Americans might flinch at the idea that US politics has anything in 
common with the Philippines or Russia. But, in fact, Mr Trump — who 
looks certain to secure the Republican presidential nomination — 
exhibits many of the characteristics of the current crop of strongman 
leaders, including Messrs Putin, Xi, Erdogan, Sisi, Modi, Orban and 
Duterte.
All these men have promised to lead a national
 revival through the force of their personalities and their willingness 
to ignore liberal niceties. In many cases, the promise of decisive 
leadership is backed up by a willingness — sometimes explicit, sometimes
 implied — to use illegal violence against enemies of the state.
“Duterte
 Harry” has played up his links with vigilante gangs. Mr Putin’s use of 
brutal tactics in the second Chechen war was well known to Russian 
voters. Mr Modi’s alleged role in a 2002 massacre in his home state of 
Gujarat was sufficiently controversial to get him banned from the US for
 many years. 
Mr Sisi secured his grip on power with a 
massacre on the streets of Cairo. And, even in the law-governed US, Mr 
Trump has promised to torture terrorists and murder their family 
members.
Strongman leadership usually goes hand-in-hand
 with extreme sensitivity to criticism. In both the Putin and Xi 
presidencies there have been crackdowns on freedom of speech. In Turkey,
 Mr Erdogan has sued almost 2,000 people for defamation. Mr Trump misses
 few opportunities to insult the media and has said that he would like 
to make it easier for politicians to sue the press.
Typically,
 strongman leaders trade on feelings of insecurity, fear and 
frustration. Mr Putin and Mr Erdogan have portrayed Russia and Turkey as
 surrounded by enemies. Mr Sisi has promised to rescue Egypt from 
terrorism. Mr Xi and Mr Modi have capitalised on ordinary people’s 
frustrations with corruption and inequality. The Trump campaign has 
incorporated elements of all these themes, promising to reverse national
 decline and get tough with criminals and foreigners.
At
 a time when Barack Obama, the US president, and Angela Merkel, the 
German chancellor, are both cautious, deliberative internationalists, 
the risk-taking nationalism of Mr Putin has attracted admirers in China,
 the Arab world and even the west.
Mr Trump and Mr 
Putin seem to have formed something of a mutual admiration society. 
Strongman leaders often get on very well — at least initially. But 
because their relationships are based on a shared style and swagger, 
rather than underlying principle, they also often fall out 
spectacularly.
Mr Erdogan used to have close 
relationships with Mr Putin and with President Bashar al-Assad of Syria 
but these have turned into bitter enmities. Further back in history, the
 1939 pact between Hitler and Stalin gave way within two years to war 
between Germany and the Soviet Union.
The alarming 
truth is that the impact of strongman leaders is rarely confined within 
national borders. All too often, the undercurrent of violence that they 
introduce into domestic politics spills over on to the international 
stage.
