Example Input: Kim Jong Nam is the exiled half brother of North Korean leader Kim Jong Un. Here he is pictured at Beijing airport in China in 2007.
As of 2003  he lived in exile in Macau and other neighbouring regions  after falling out of favour with  his father who accused him of turning "into a capitalist " according to an email sent to the editor of the Tokyo Shimbun by Kim Jong Nam . He said: "After I went back to North Korea following my education in Switzerland  I grew further apart from  my father  because I insisted on reform and market-opening and was eventually viewed with suspicion."
In 2012   Kim Jong Nam  heavily criticised  his  family's North Korean leadership.  He  said: "The Kim Jong-un regime will not last long. Without reforms  North Korea will collapse  and when such changes take place  the regime will collapse " according to excerpts from Japanese journalist Yoji Gomi in Tokyo Shimbun newspaper.
On February 13  2017   Kim Jong Nam  was about to leave on a flight to Macau where  he  lived with  his  wife and two children.
But  he  died on  his  journey. South Korea was quick to accuse North Korea of dispatching a hit squad to murder  him  at the airport in Kuala Lumpur  saying two female assassins poisoned  him  and then fled in a taxi.

Example Input: Itâs always the anniversary of something or other. In November  we have the Russian Revolution and the Balfour Declaration  and this week marks the 500th year since  Martin Luther  challenged the Catholic Church with  his  95 theses. Given the loopy Zeitgeist of our times  I should rush into the street and mark the occasion by defacing Protestant churches with the customary red paint of protest. Luther  after all  was more than the creator of Protestantism. He was also a rotten anti-Semite.
But does  Luther  also deserve a splash of red? The evidence is pretty shocking  not to mention definitive. In 1543   he  published âOn the Jews and Their Lies â in which  he  called my ancestors âbase and whoring peopleâ full of the âdevilâs feces . . . they wallow in like swine.â
 He  had all sorts of ideas for what to do with the Jews  including the wholesale liquidation of their synagogues  even homes  and a ban on the teaching of their rabbis âon pain of loss of life and limb.â
To be sure  Lutherâs Jew-hatred was typical for the time  but  Luther himself  was hardly typical.  He  was a powerful  colloquial writer  and  his  words surely had some effect.  He  was the founder of a church  or a movement  that now numbers nearly 1 billion.
But more pertinently   he  provided a religious imprimatur to German anti-Semitism  which culminated in the Holocaust.  Luther  was often cited by the Nazis  but it would be wrong to blame  him  alone for the murder of 6 million souls.
As far as Iâm concerned   Luther  is a flawed figure. I can appreciate â even applaud â  his  reforms  but they mean little to  me . Nevertheless  I spare  him  the red paint because I know  his  Jew-hatred is hugely negligible compared with the Reformation  he  initiated and  not insignificantly  the role  he  played in encouraging literacy.  He  wrote in German  not Latin  and like the Hebrews  he  so despised   he  interposed no one between man and God. One had to read the Bible.
I pick and choose  my symbolic can of red paint always at the ready. But when it comes to those Confederate generals  they unambiguously stand for slavery  racism and the vile nostalgia for the so-called Lost Cause that prompted the erection of so many memorials. I cherish my Bach  feel bully about T.R. and acknowledge the immense importance of Martin Luther. He did more good than bad.

Example Input: Cruz 's fans say it 's because he stands on principle . 
In the three years since he arrived in the U.S. Senate , Ted Cruz has become easily the most hated man in Washington -- a fact he 's now using to his advantage as a presidential candidate . 
Is it true , as Cruz would have it , that the dreaded GOP establishment pays lip service to shrinking the federal government and repealing Obamacare , but actually would prefer to preserve the status quo ? 
Or do Cruz 's Beltway critics have a point ? 
Cruz has n't hesitated to take polarizing stances , even when doing so means taking on his Republican colleagues . 
Lee is also Cruz 's best friend -- maybe his only friend -- in the Senate . 
In his memoir , Cruz writes that no one stood by him "more courageously or indispensably" than Lee during his 21-hour anti-Obamacare speech that preceded the 2013 government shutdown . 
When Lee brought up his bill in the committee hearing , he was n't sure if he 'd have Cruz 's support . 
Cruz attacked the bill as dangerous and politically poisonous . 
Cruz went on to warn his fellow senators that if they voted for the bill , they would imperil their careers . 
Essentially , Cruz was saying that the legislation would let dangerous people out of prison , they would commit more crimes , and the senators would be subject to Willie Horton-style attack ads . 
Lee , who was sitting right next to Cruz , could not believe what he was hearing . 
Lee 's communications director , Conn Carroll , confirmed to me that Lee and his staff had no advance warning that Cruz was planning to brutally attack -- and , in Lee 's view , misrepresent -- his friend 's bill . 
The bill made it out of committee that day , but now it appears to be in trouble , with several other Republican senators taking Cruz 's line against it at a Senate lunch last week . 
Today , Lee has conspicuously joined every other sitting senator in declining to endorse Cruz 's presidential run . 
And while Lee and Cruz are still friends , the episode vividly illustrates Cruz 's talent for irritating other senators . 
Another telling episode came during the 2013 government shutdown , which Cruz spearheaded , insisting that if Congress defunded Obamacare , the president might go along . 
As McKay Coppins reports in his new book , The Wilderness , Cruz 's own staff never actually expected the gambit to work . 
To Cruz 's colleagues , it was a pointless and damaging exercise , but grassroots conservative groups cheered the effort . 
Cruz is close to the Fund and has appeared in its ads . 
At a private lunch of Republican senators , New Hampshire Senator Kelly Ayotte waved the document in Cruz 's face and demanded that he disavow it . 
When he declined , several other senators , including then-Minority Leader Mitch McConnell , took Ayotte 's side and denounced Cruz . 
In my conversations with Republican policy types and Senate aides about Cruz , this lack of regard for his colleagues , and for the niceties that have traditionally governed the upper chamber , was a common theme . 
As Trent Lott , the former Senate majority leader , told me last week , referring to the time Cruz called McConnell a liar on the Senate floor : "You just do n't do that . 
Another criticism of Cruz is that his antics are disruptive and damaging to the Republican Party . 
Cruz does have policy differences with the business wing of the party : Unlike the Chamber , he opposes comprehensive immigration reform , would like to kill the Export-Import Bank , and -LRB- in a reversal -RRB- opposed a recent free-trade bill . 
In Iowa , Cruz has been subjected to millions of dollars in attack ads and personally criticized by the Republican governor , Terry Branstad , for opposing ethanol subsidies . 
But a Republican policy expert close to a number of top GOP operatives and donors insisted it 's not about Cruz 's style or his positions . 
But the effort does n't result in smaller government or the end of Obamacare -- all it achieves is drawing attention to Cruz . 
You can see how these complaints look from the perspective of Cruz and his fans : like features , not bugs . 
But what about the criticism that Cruz 's efforts have n't gotten any results ? 
The Cruz camp did n't reply to my query , so I put the question to Amanda Carpenter , who was Cruz 's communications director during much of his time in the Senate , including the shutdown . 
Carpenter said Cruz had sent a message . 
Cruz has shown that one person can make a difference ." 
But as they see it , the difference Cruz has made in the Senate has not been a positive one .

Ted Cruz
