MSNBC host Rachel Maddow on Thursday night criticized Republicans in the Senate for believing in a conspiracy theory about the United Nation’s Arms Trade Treaty.

“It seems like Republicans and conservatives and people who voted for Mitt Romney are more susceptible than the rest of America to conspiracy theories, especially about people being out to get them,” she remarked. “And looking at the way the elected Republicans approach governing right now might be a clue as to why Republicans are more susceptible to conspiracies than the rest of us.”

The UN General Assembly on Tuesday approved a treaty to regulate the multibillion-dollar international weapons trade. The first-of-its-kind treaty attempts to prevent tanks, missiles, helicopters, warships, small arms, and other weapons from being sold to human rights abusers or terrorist groups.

But Senate Republicans and a few conservative Democrats plan to oppose the treaty because they believe it is a plot to implement new gun control laws in the United States. The Senate needs a super-majority of 67 votes to ratify the treaty.

“Our country is almost certain to end up on the same side of the issue as… Iran, Syria and North Korea,” Maddow observed.

“Conspiracy theories can be fun, but when they start seeping into the way one of our two political parties approaches basics of governing, they’re less fun. Maybe we should give the lizard people a shot at running things around here?”
