After the COVID lockdowns, the Western global leadership class had little credibility left. So it seemed insane when they immediately pivoted to a new crisis — but that’s exactly what they did.

Russia’s invasion of Ukraine triggered demands from elites in Europe and America for NATO-aligned nations to involve themselves in the conflict. Many Republicans were initially on board, with Fox News and CNN marching in lockstep behind intervention. But the Republican base quickly soured on the war once it became clear that U.S. involvement didn’t serve American interests.

If the situation really is dire, let the Trump administration make its case to the people. Present the evidence. Debate it in Congress. Vote.

In a strange inversion, the right became anti-war while the left championed military escalation.

That reversal matters now, as some in the GOP look to drag the country into another long conflict. We should remember what Ukraine taught us.

When Russian President Vladimir Putin invaded, many conservatives instinctively aligned with Ukraine. The Soviet Union had been an evil empire and a clear enemy of the United States. It was easy to paint Russia as an extension of that threat. President Biden assured Americans that there would be no boots on the ground and that economic sanctions would cripple Russia quickly.

But the war dragged on. Hundreds of billions of dollars flowed to Ukraine while America entered a painful economic downturn. Conservatives began asking whether this was worth it.

Putin was no friend of the U.S., and conservatives had valid reasons to distrust him. But suddenly, anyone questioning the war effort was smeared as a Russian asset. Opposition to the war became an extension of the left’s deranged Russiagate conspiracy, which painted Donald Trump as a blackmailed Kremlin agent.

Some Republican politicians kept pushing the war. Fox News stayed hawkish. But much of the conservative commentariat broke ranks. They knew that the boys from Appalachia and Texas — exactly the kind of red-state Americans progressives despise — would again be asked to die for a war that served no clear national purpose.

From that disillusionment, conservatives drew hard-earned lessons.

They saw that U.S. leaders lie to sustain foreign conflicts. That politicians in both parties keep wars going because donors profit. That Fox News can become a mouthpiece for military escalation. That you can oppose a war without betraying your country. And that American troops and taxpayer dollars are not playthings for globalist fantasies.

“America First” began to mean something real: Peace through strength didn’t require constant intervention.

Unfortunately, many of those lessons evaporated after the Hamas terrorist attack on Israel on Oct. 7.

That attack was horrific. No serious person denies the brutality of Hamas or questions Israel’s right to defend itself. But Prime Minister Benjamin Netanyahu has treated the attack as a green light to target longtime adversaries, including Iran. As a sovereign nation, Israel can pursue its own foreign policy. But it cannot dictate foreign policy for the United States.

In 2002, Netanyahu testified before Congress that Saddam Hussein was developing nuclear weapons. He said toppling both the Iraqi and Iranian regimes would bring peace and stability. He was wrong.

He wasn’t alone, of course. Many were wrong about weapons of mass destruction and the Iraq War. But Netanyahu’s track record is highly relevant now. While conservatives once fervently supported the Iraq invasion after 9/11, many — including Tucker Carlson and Dinesh D’Souza — have since apologized. They admit they got it wrong.

Afghanistan, while flawed, had clearer justification. The Taliban had harbored Osama bin Laden and al-Qaeda. But the lies about weapons of mass destruction and failed nation-building in Iraq turned that war into a conservative regret.

In March, Director of National Intelligence Tulsi Gabbard testified that Iran had not resumed efforts to build a nuclear weapon. Gabbard, like Trump allies Robert Kennedy Jr., Kash Patel, and Pete Hegseth, was chosen precisely for her skepticism of the intelligence bureaucracy. Trump remembers how his first term was sabotaged by insiders loyal to the status quo. This time, he selected appointees loyal to the voters.

Gabbard’s assessment contradicts Netanyahu, who claims Iran is months away from having a bomb. That’s a massive discrepancy. Either Iran hasn’t restarted its program, or it’s on the brink of building a nuke.

So which is it?

Did U.S. intelligence fail again? Did Gabbard lie to Congress and the public? Or did she simply say something the ruling class didn’t want to hear?

Trump, Gabbard, and Vice President JD Vance understand how Iraq went wrong. They know Americans deserve evidence before another war — especially one that risks dragging us into a region we’ve already failed to remake at great cost.

Yet the war hawks keep repeating the same lie: This time, it’ll be quick. The United States is too powerful, too advanced, too economically dominant. The enemy will fold by Christmas.

Biden said the same about Ukraine. And hundreds of billions later, we remain in a grinding proxy war with Russia.

Now, while still financing that war, Americans are told they must back a new war — this one initiated unilaterally by Israel. The U.S. faces domestic strife, crippling debt, and an ongoing open-border crisis. Involvement in yet another conflict makes no sense.

Israel may be right about Iran. Tehran may indeed have developed a nuclear program behind the world’s back. But if Israel wants to wage a war, it must do so on its own.

The Trump administration has made clear that it wasn’t involved in Israel’s pre-emptive strikes and didn’t approve them. If Israel starts a war, it should fight and win that war on its own. America should not be expected to absorb retaliation or commit troops to another Middle Eastern project.

These wars are never short, and they are always expensive.

Even if Iran’s regime collapses quickly, the aftermath would require a long, brutal occupation to prevent it from descending into chaos. Israel doesn’t have the capacity — let alone the political will — for that task. That burden would fall, again, to America.

So before conservatives fall for another round of WMD hysteria, they should recall what the last two wars taught them.

If the situation really is dire, let the Trump administration make its case to the people. Present the evidence. Debate it in Congress. Vote.

But don’t sleepwalk into another forever war.
