Chris Wallace has posed an perfectly legitimate question to United States ambassador to the United Nations Nikki Haley.

The “Fox News Sunday” host asked Haley this morning why the Trump administration is so willing to use military action against Syria when it uses chemical weapons on its citizens but doesn’t deliver such punishment when the Syrian government kills them with “conventional weapons.”

“That’s an unfair question,” Haley said in her initial response.

Actually, Mme. Ambassador, it’s a perfectly fair question and Wallace was correct to ask it.

For the record, Haley said the United States doesn’t tolerate the use of any weapons, but didn’t respond directly to Wallace’s query about whether the president views chemical weapon use differently than conventional weapon use.

I happen to support the decision to strike at Syria. I believe we responded correctly by aligning ourselves with France and Great Britain and hitting the Syrians in concert with our allies.

My belief now is that we need to reignite some intense diplomatic power to persuade the Syrians it clearly is in their best interests to call a halt to the slaughter in their country.

Oh, and while we’re at it, we also need to ratchet up the pressure on Russia and Iran to cease lending aid to a war criminal — Bashar al Assad — who happens to be the dictator who runs a ham-fisted government in Damascus.

So, here we are. We have pounded the Syrian chemical weapons infrastructure. Our forces reportedly delivered crippling damage to it. Ambassador Haley said the strikes have set back Syria’s chemical weapons program by many years.

What about those conventional weapons? When do we draw the “red line” when it involves the hideous use of those weapons on innocent victims?
