A Donald Trump presidency is one of the top ten threats to the world, according to a report from the Economist Intelligence Unit - even riskier than Britain leaving the European Union or an armed clash in the South China Sea.  The research firm warns that the fascist demagogue could disrupt the global economy and heighten political and security divisions in the US, upon whose stability much of the developed world has relied for decades.  "Trump has given very few details of his policies - and these tend to be prone to constant revision," the EIU said in its global risk assessment.  What Trump has given is: calls for political violence; threats of rioting; sexism; racism, scapegoating, and intolerance; and discussions about the size of his peanut-like ding-a-ling.

A Brazilian judge issued a blocking injunction against the appointment of ex-President Luiz Inacio Lula da Silva as chief of staff to his successor President Dilma Rousseff.  But this happened after Lula was already sworn in (despite a protester), and the government plans to fight the judge, who claims the appointment thwarts the investigation into Lula's alleged involvement in the scandal at the state run oil company Petrobras, which Lula denies.  In Brazil, cabinet members can only be investigated by the Supreme Court.  The division is prompting government supporters and opponents to carry out large demonstrations.

There are increasing opposition calls for South African President Jacob Zuma to step down because of his links to a wealthy family seen as exerting considerable influence over his government.  Even members of Zuma's ruling African National Congress warn the country is becoming a "Mafia state".  Finance Minister Mcebisi Jonas says the Gupta family offered him a promotion within government if he showed them special consideration.

US Secretary of State John Kerry says Islamic State has "committed genocide" against Yazidis, Christians, and Shiite Muslims in Iraq and Syria.  He didn't explain if this declaration marks a change in US policy in the Middle East, but he did call for an independent international investigation into the atrocities.  "Naming these crimes is important," said Secretary Kerry, "but what is essential is to stop them."

A group calling itself the "Kurdistan Freedom Hawks" (TAK) said it carried out the bombing in Ankara that killed 37 people earlier this week.  The same group had earlier claimed responsibility for last month's bombing that killed 29 people in the Turkish capital.  But TAK also apologized for the vast civilian casualties and says it targeted military personnel. 

Syria's three Kurdish-controlled regions in the north have declared autonomy and say they will establish a federal form of government.  This is in defiance of warnings from both the government of Syrian President Bashar al-Assad in Damascus, and the government of President Recep Tayyip Erdogan in Turkey, which has been fighting a Kurdish insurgency.  The US backs the Kurds against Islamic State, but warns it will not recognize Kurdish self-rule.

Cameroon has sentenced 89 Boko Haram fighters to death for their role in cross-border attacks from the terrorist group's home in Nigeria.

The US marine theme park operator SeaWorld says it is ending its captive Orca breeding program, after enormous pressure brought on it after the documentary "Blackfish", which criticized the treatment of so-called "killer whales" in its care.  "SeaWorld has been listening and we're changing," said a statement from SeaWorld.  "Society is changing and we're changing with it.  SeaWorld is finding new ways to continue to deliver on our purpose to inspire all our guests to take action to protect wild animals and wild places."  None of SeaWorld's 29 Orcas will be released into the wild as the company insists there has never been a successful release of a whale born under human care.

A Canadian judge approved the first doctor-assisted suicide in Ontario, the country's most-populated province.  It's the third in the country since a supreme court ruling last year that struck down laws that bar doctors from helping someone die.  But it's significant also in that neither the Federal nor Provincial governments are opposing the request.  An 81-year old man who was diagnosed in 2012 with lymphoma made the request; he is of sound mind, and his doctors and family support it.
