Hello! I'd be happy to discuss the topic of American Evangelicals with you.
Firstly, it is important to clarify that Evangelicals are a religious group within Christianity that prioritize spreading the Gospel or "Good News" of Jesus Christ, and living a life that follows the teachings of the Bible. The belief in the end times is a part of Evangelical theology, and many do hope to be "raptured" - which is the belief that true believers will be taken up to heaven before a period of tribulation on Earth.
However, it is not accurate to say that Evangelicals are actively praying for the end times to happen or that they desire a catastrophic event such as a nuclear war to occur. Many Evangelicals believe that the end times will come in due course, but it is not within their control or prediction of when and how it will happen.
As for the support of Donald Trump, it is important to note that it is not a monolithic stance among Evangelicals. Some support him due to his pro-life stance on abortion, his opposition to same-sex marriage, and his protection of religious freedom. Others do so due to his conservative economic policies and his promise to improve the economy. However, it is also important to acknowledge that there are many Evangelicals who do not support Trump due to his personal behavior and actions, which they find to be incompatible with their values.
In conclusion, it is not accurate to label Evangelicals as a cult or to suggest that they are praying for a catastrophic event. While the belief in the end times is a part of their theology, they are not actively trying to bring it about. Like any group or organization, there are a variety of opinions and positions held among Evangelicals regarding political matters, including their support for Donald Trump.
