U.S. President Joe Biden mentioned South Korea, Samsung and Kim Jong-un during the first presidential debate ahead of November's U.S. election.

During the debate in Atlanta, Ga., Biden mentioned South Korea as one ally that support the U.S. foreign policy of providing financial and military support to Ukraine.

"I got 50 other nations around the world to support Ukraine, including Japan and South Korea, because they understand that this kind of dislocation has a serious threat to the whole world peace," Biden said during the debate, which aired on CNN.

Biden, 81, tackled one of his biggest weaknesses — his age and fitness for office — by sharing how he created thousands of jobs and generated millions of dollars in state revenues.

"I convinced Samsung to invest billions of dollars here in the United States. And then guess what? Those fabs, they call them, to — to build these chips, those fabs pay over $100,000. You don't need a college degree for them. And there's billions, about $40 billion already being invested and being built right now in the United States, creating significant jobs for Americans all over — from all over the world," he said.

While praising the U.S. as the most progressive and the strongest country in the world, Biden argued that even North Korean leader doesn't want to want to engage in conflict with with the U.S.

"Those who he (Trump) cuddles up to, from Kim Jong-un who he sends love letters to, or Putin, they don't want to screw around with us," Biden said.

Former U.S. President Donald Trump slammed Biden's military policies, saying that he would drive the country into World War III.

"We are very, very close to World War III, and he's driving us there. And Kim Jong-un of North Korea, President Xi (Jinping) of China and (Vladimir) Putin (of Russia) don't respect him. They don't fear him," Trump said.
