In the greatest crisis this world has experienced since the world wars, we need leaders who can keep a level head, communicate clearly to the people they're leading, and show compassion and humility. We've seen or heard about the egotistical rantings of the current U.S. president. In stark contrast, it's great to hear from true leaders who exhibit the characteristics I've listed.
The true "leader of the free world," now that the U.S. has a president who's abdicated that role, is perhaps, as noted in New York magazine's Intelligencer, Angela Merkel ("The Leader of the Free World Gives a Speech, and She Nails It"). Give a listen to (or read the subtitles) what she has to say about the crisis to the people of Germany.
"We are a democracy. We don't live by being forced, but by sharing knowledge and collaboration."
As a thought leader in U.S. politics, Bernie Sanders has been promoting a platform that seems like it was custom made for our current situation. That's one reason he comes across so authoritatively in this video.
