Amid escalating tension between the relationships of the US and Russia, President-elect Donald Trump said America must need to expand its nuclear capability.

Trump issued the statement after Russian President Vladimir Putin said that Russia's arsenals are better and stronger than any country in the world. Data from US Arms Control Association revealed that the US has 7,100 nuclear weapons while Russia has 7,300.

"The United States must greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes," said Trump on his Twitter account.

He also said that the US must carefully monitor any changes in the balance of power and in the political-military situation in the world, especially along Russian borders.

"And quickly adapt plans for neutralizing threats to our country," he said.
