signed the Arms Trade Treaty, calling it a “significant step” for securing global peace. The treaty would track the sale of tanks, combat vehicles, combat aircraft, missiles and small arms.

However, many Republicans and pro-gun groups like the National Rifle Association (NRA) insist the that the U.S., which is the world's largest exporter of firearms, should not ratify the treaty because it could also stifle the Second Amendment rights of Americans.

Napolitano began a Fox & Friends segment about the Arms Trade Treaty on Thursday by debunking the notion that the right to keep and bear arms could be curtailed.

"That is guaranteed in the Second Amendment, and a treaty cannot trump an expressed guarantee in the Constitution," Napolitano explained.

But the discussion quickly veered into conspiracy theory as host Brian Kilmeade interrupted: "Until we get that world government."

"But you know what, Brian, the people that are behind this treaty want that world government," Napolitano insisted. "And in their minds, this is a step toward it... Eventually controlling all of us."

"That's the value set of John Kerry, Barack Obama and their allies in Europe who pushed this treaty," he added. "Theoretically, the Constitution should trump anything that's inconsistent with it. We know that doesn't happen because of Obamacare. Absolutely inconsistent with the Constitution, and they found some crazy, cockamamie, never-used-before nonsense about 'it's a tax, therefore, it's lawful.'"

"So, if a government doesn't like pink dresses, it can tax them so that you can't wear them," the former New Jersey Superior Court judge opined, pointing to co-host Elisabeth Hasselbeck's dress. "Well, you can always afford them no matter what the tax is, but you know what I mean."

In the end, Napolitano predicted that the U.S. Senate would never ratify the treaty because Senate Majority Leader Harry Reid (D-NV) would "lose his job" and gun ownership was a "natural guaranteed right that you can't interfere with."
