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."
