For an influential group of American Christians, support for Israel -- and hatred of Iran -- are based in a biblical prophecy.
When President Trump authorized the drone strike that killed the powerful Iranian general Qasem Soleimani, he wasn't just flexing America's muscle in the Middle East.
He was also acting on the advice of a politically powerful group of evangelical Christians who believe that the US and Israel are part of the Bible's plan to bring about the second coming of Jesus.
Once considered a fringe element of the religious right, evangelical Christian Zionists are playing an increasingly visible role in Republican politics. Today, unprecedented access to the Trump administration has given them an opportunity to reshape the Middle East.
A previous version of this video misstated, at 1:40, the percentage of Americans who are Christian but neither Evangelical nor Catholic. The error has been corrected.
