Donald Trump is the "Churchillian" leader the United States needs, and is the clear choice in a "historic" presidential race that does not pit an establishment Republican against a liberal Democrat, Jerry Falwell Jr., one of Donald Trump's early presidential race endorsers writes in an opinion piece for The Washington Post.

"We are at a crossroads where our first priority must be saving our nation," writes Falwell, the president of Liberty University. "We need a leader with qualities that resemble those of Winston Churchill, and I believe that leader is Donald Trump. As Churchill did, Trump possesses the resolve to put his country first and to never give up in a world that is increasingly hostile to our values."

President Barack Obama and Democratic nominee Hillary Clinton, his one-term secretary of State, remind Falwell of another historical character: Neville Chamberlain, the British Conservative prime minister who is is best known for signing the Munich Agreement in 1938, relinquishing a region of Czechoslovakia to Adolf Hitler's Nazi regime.

And, he writes, the nation's $150 billion nuclear deal with Iran will clear the way for that country, "the leading state sponsor of terrorism in the world and a nation committed to the destruction of Israel," to become a nuclear power. The deal reminds Falwell of Chamberlain's deal with Hitler.

Falwell points out in his opinion piece that Americans were "forced to choose" between a liberal Democrat [Barack Obama] and "weak establishment Republicans" [John McCain and Mitt Romney] in 2008 and 2012. After Obama won, Americans in the 2010 and 2014 midterms put Republicans in control of Congress, but "still nothing changed," Falwell writes.

In addition, he says, the policies of Obama and Clinton had the "intended or unintended" effect of breathing life into the Islamic State, and the "feckless establishment" GOP-led Congress enabled them.

Obama and Clinton also pushed the nation's debt to $19 trillion, and law enforcement has been "demonized" by them, he continues.

Falwell warns in his article there will be "dire consequences" if Americans don't unite between Trump and his running mate, Indiana Gov Mike Pence.

"If Clinton appoints the next few Supreme Court justices, not only will the Second Amendment right to bear arms be effectively lost, but also activist judges will rewrite our Constitution in ways that would make it unrecognizable to our founders," said Falwell.
