Ethan Hawke Explains How Pope Francis Can Bring Peace To Ukraine [Watch]

Ethan Hawke has shared his idea on how Pope Francis, the current leader of the Catholic Church, can bring peace to Ukraine and end the Russian invasion.

"I had this idea that I wanted to write the pope, and say to him that Francis of Assisi marched across the desert to the battlefield in the fifth crusade to try to have audience with the sultan," Hawke said on "The Late Show With Stephen Colbert" Tuesday. "And he did this huge act of peace."

The 51-year-old actor further explained if the pope ever goes on a march, it should be from Belarus (Europe) to Mariupol (Ukraine). He also suggested that "we would all go" to attend this march, which he believes could bring the refugees back to their homes.

"And, like, priests and rabbis, and we could all go and say you have to stop killing children," the "Before" trilogy star added. "The choice shouldn't be whether to escalate the war, or for democracy to fail."

Hawke went on to share his thoughts about how "grown-ups" should step into the situation and say that bombing and killing children is not allowed. Furthermore, he proposed that everyone should focus their energy on taking care of the Earth and dealing with real crises, hinting at global warming.

"I feel like the grown-ups of the world need to stand up and say, 'You're not allowed to bomb and kill children. You're not allowed to do it. You gotta behave like a grown-up,'" the actor said. "And that way we could focus our energy on taking care of the planet and address the real [crises] that are happening right now, instead of making them up."

Hawke explained that Pope Francis has a "rare global platform" that can make a huge difference.

"Where are the voices of people to ask us to join together?" he said further. "And I feel like he's one of the very few people I can think of that has that moral authority."

Hawke is not the first celebrity to voice out his opinions about the Russia-Ukraine conflict. Many celebs, including Ashton Kutcher, Olga Kurylenko, Maksim Chmerkovskiy and Milla Jovovich have also been vocal about the ongoing war.
