An American's grueling bike ride across Europe, the Middle East an Asia

Last year, Ian Andersen began a cross-continent bike ride from the edge of Portugal to Japan. Along the way, he got caught in Iran as Israel carried out attacks on the country. Later, he got stuck in Mongolia for weeks as he awaited a visa to travel through China. As The World's Jeremy Siegel reports, his trip - shared in videos on Instagram and TikTok - has gained a massive following online and highlighted changing perceptions of Americans in a shifting world order.
