If you had just arrived from Mars to observe the Republican and Democratic conventions, one after the other, you undoubtedly would conclude that they were talking about two different countries.

One America recognizes real threats from foreign jihadi fighters who seek to eradicate our existence and to replace our freedoms with Islamic sharia law. It believes that economic revival — through tax reform, trade reform, and enforcing our borders and immigration laws – holds the key to future prosperity.

The other America believes we face no real foreign threats, the economy is doing great, and that our biggest challenge comes from crop failures, rising seas, and monster storms caused by — you guessed it, climate change.

It wasn’t by chance that the Democrats made no mention of ISIS on the first day of the convention and scarcely mentioned it on the next two days.

Terrorism and Islamist ideology that seek to replace our democratic republic with a “superior” law written by Allah are a distraction from the real mission of Democrats in Philadelphia. As former Maryland Governor Martin O’Malley put it: “to hell with Trump’s American nightmare.”

In his first year in office, President Obama directed the Central Intelligence Agency to divert significant assets from the war against real threats from terrorists and enemy nations to the hypothetic dangers of “climate change.”

The Defense Department was ordered to follow suit, and under Obama’s direction, launched massive building programs at American naval bases to shelter them from rising seas.

President Obama squandered billions of U.S. taxpayer dollars in pursuit of an ideological agenda.

This past May, the CIA quietly shuttered its climate change initiative, since it was unable to find data to sustain the Left’s faith in its new religion that man-made climate change would destroy the earth, or significant portions of it.

Cyclical changes in our climate have always occurred and have had dramatic impacts in the past, long before the carbon emissions the Left blames for today’s droughts and tsunamis.

Hollywood actress Signourey Weaver, hair on fire, introduced a “scare-me” video by James Cameron and claimed that farmers in Kansas were losing their crops today because of climate change.

I understand that Ms. Weaver is too young to have lived through the Dust Bowl — so am I. But I would hope she isn’t too dumb to have read about it and to have understood that these things have happened before, and will happen again.

Government’s role, in such circumstances, is to extend a helping hand of solidarity to individuals who lose their livelihoods to disasters they had no way of foreseeing. Its role is not to preemptively cripple the nation with fantasy-driven regulations and shut down entire sectors of the economy.

Incapable of a sustained conversation about national security, we’re left with Sen. Harry Reid suggesting that the Director of National Intelligence should “fake” national security briefings to Donald Trump. Why? Because Trump suggested that perhaps the Russians might be able to find the 33,000 emails Hillary Clinton admitted she deleted from the private server even President Obama warned her not to use.

In Senator Reid’s mind, entrusting Mrs. Clinton with our national security secrets is just fine, even though FBI Director James Comey acknowledged she had been “extremely careless” by transmitting highly-classified intelligence information on her personal email server. Let’s not forget that the FBI still hasn’t found more than 2,000 classified emails Mrs. Clinton deleted.

Bill Clinton thought he had found a “trump” card that would earn his wife a place in the pantheon of national security heroes.

“She launched a team — and this is really important today — she launched a team to fight back against terrorists — online — and built a new global counterterrorism effort,” he said.

Think about that for a moment. In the words of her own husband, Mrs. Clinton’s main achievement in the war against the terrorists attacking us was to hire a few social media analysts whose advice she didn’t consult and in fact ignored when they informed her the Benghazi attacks had nothing to do with a YouTube video insulting Mohammad.

I’ve got news for the Clintons: our intelligence community has been focusing on social media for years. The biggest growth industry among the Beltway bandits is foreign language experts who can mine Facebook, Twitter and other social media sites for evidence of jihadi connections.

That’s great, but it isn’t enough.

Former Defense Secretary Leon Panetta went overboard in his support for Mrs. Clinton, claiming that, if elected, she would take office as someone who “has the trust of our troops who know she will always have their back.”

Four men died in Benghazi because Mrs. Clinton didn’t have their backs. Instead of rushing to the rescue, she spent hours in meetings trying to keep Panetta from sending reinforcements to their rescue.

But that’s the other America. The America of facts.

The differences of our two Americas are many. One America lionizes the mothers of young black men killed by the police – often after they had committed assaults of one sort or another. The other celebrates as heroes police officers gunned down by snipers seeking vengeance.

One America believes that women, illegal immigrants, invalids, minorities, and people with kaleidoscope glasses constitute grievance classes who deserve special treatment. The other believes that all Americans deserve equal treatment under the law and equal opportunity under our system.

As a life-long investigative reporter, I remain committed to the facts. But I recognize that the contest in November will be determined not by facts, but by faith, and by how many believers on each side come to the polls. That is the new reality of the two Americas of 2016.
