I'd say that on the bright side if Trump starts a war he won't be reelected...
I am not sure Trump sees it that way:
Trump Turns to Evangelicals After US Strike on Iranian Commander
MIAMI (Courthouse News) – Amid increased tensions with Iran, President Trump sought to shore up support among evangelical voters at a massive Miami church Friday night, led by a self-described apostle who claims his ministry has brought dead babies back to life through a portal to God.
The rally at the King Jesus International Ministry Church came the night after a Trump-ordered air strike killed Iranian Major General Qasem Soleimani and Iraqi commander Abu Mahdi al-Muhandis near a Baghdad airport.
….Trump discussed the Iran crisis briefly at the church rally before turning back to themes of religious freedom. The president told a sprawling crowd that Democrats are conspiring to “shut out God from the public square so they can impose their anti-religious and socialist agenda.”
… “He’s the first president in a long time who actually has testicles,” the South Florida resident said. “Democrats don’t like him, so whatever he does, no matter if it’s good or bad, they will speak against him.”
…The Pew Research Center’s exit polling data from 2016 suggested that roughly 8 in 10 white voters who identified as evangelical or born-again Christian voted for Trump.
The mentality of the Crusades is still with us. Trump may be gambling that he can use that mentality in his old "us versus them" game. You are either "with us" or with "them" the evil outsiders who are against motherhood, apple pie, and Christianity.
