Friday's stabbing in London has now become a campaign issue in the UK's snap general election, which is set for Dec. 12. Prime Minister Boris Johnson is blaming the opposition Labour Party for the incident — which has upset many, including the father of one of the victims. And, NATO is celebrating 70 years this week in London. It will be a low-key affair, considering US President Donald Trump's dismissive statements about the mutual defense treaty. Further dampening the celebration are recent statements from French President Emmanuel Macron, who said, "What we are currently experiencing is the brain death of NATO." Also, the word "existential" is Dictionary.com's word of the year.
