Actor George Takei is warning President-elect Donald Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?' Romney: 'Unthinkable and unacceptable' to not commit to peaceful transition of power Two Louisville police officers shot amid Breonna Taylor grand jury protests MORE that nuclear weapons are "no game."

In an op-ed published Thursday in The Daily Beast, Takei cited a recent tweet by the president-elect, which said the U.S. "must greatly strengthen and enhance its nuclear capability" until the world "comes to its sense regarding nukes."

"I can’t help but feel Mr. Trump treats brinksmanship as some game," he wrote in the piece.

"It’s hard to believe he needs reminding, but nuclear weapons are not toys, nor are they chips to be wagered in some kind of high stakes poker match."

Takei said he is one of a number of people who remember the first time atomic weapons were used.
