The issue was a key topic of debates among administration officials this summer, and many of them have objected to the idea, including Secretary of Defense Ash Carter and Secretary of State John Kerry, the newspaper reported, citing unidentified administration officials.

In particular, Carter argued that Russian President Vladimir Putin and North Korean leader Kim Jong-un could interpret a promise of no first use as a sign of American weakness, even though that was not the intent, the report said.

In addition, advisers also warned that a no-first-use declaration would rattle allies like Japan and South Korea.

Obama has sought to make the initiative for building a nuclear-free world a key legacy of his presidency, launching the Nuclear Security Summit of world leaders aimed at reducing the stockpile of fissile material and keeping it out of the hands of terrorists.

The fourth and last Nuclear Security Summit was held in Washington earlier this year. (Yonhap)
