Donald Trump suggested during lunchtime Thursday that the country needed more nuclear weapons.

'The United States must greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes,' Trump tweeted from his Mar-a-Lago resort, just a day after meeting key Pentagon leaders, some of whom are charged with overseeing the nation's nukes.

The comments come after Russian President Vladimir Putin said his own country needed more nuclear weapons.

'We need to strengthen the military potential of strategic nuclear forces, especially with missile complexes that can reliably penetrate any existing and prospective missile defense systems,' Putin said in a speech recapping Russia's 2016 military activities.

The United States has 7,100 nuclear weapons, while Russia has 7,300, according to the Arms Control Association, a U.S.-based nonpartisan group.

President-elect Donald Trump appeared to challenge Russian President Vladimir Putin by saying the U.S. should have more nukes 'until such time as the world comes to its senses'

Donald Trump called for more nuclear weapons, following remarks by Russian President Vladimir Putin that suggested a similar uptick in weaponry

Trump's words are in sharp contrast to what President Obama hoped to be his own legacy – lowering the number of nuclear weapons in the world.

Within the first 90 days of Obama's administration, the young Democratic leader set goals for reducing the number of nuclear weapons in the world speaking to a crowd in Prague’s Hradcany Square.

His aim, the Democrat said, was 'to seek the peace and security of a world without nuclear weapons.'

However, when the Washington Post examined his record seven years later, journalists found it mixed.

Obama's Iran deal was a success, though politically problematic, with Republicans threatening its existence as the new administration comes on board.

The president had convinced about a quarter of the countries with loose nuclear materials to move those off their soil.

Additionally, along with Russia, Obama signed a new START treaty that included new weapons limits.

But the president also proposed, as part of the fiscal 2017 budget, deep cuts to spending on programs to stop nuclear proliferation.

On the flip side, military funding was left intact that allowed spending on a new generation of weapons.

'Presidents George W. Bush and Obama both noted during their campaigns that the United States and Russia are still postured on what they call a hair trigger,' former Sen. Sam Nunn told the Post in March 2016.

He had previously sponsored Senate legislation that would get the United States to assist Russia in securing its nuclear materials.

'We still have the ability to destroy each other in 30 minutes to an hour's time,' Nunn said. 'Both of them said they would improve that, and as far as I can tell, neither has.'

With these latest statements, it's more apparent that under new American leadership, neither will.

Trump was criticized over the course of his campaign for being a foreign policy amateur.

He shook up long held views on America's nuclear umbrella by saying on Fox News that Japan and South Korea should get nuclear weapons of their own, to defend themselves from the North Koreans who continually threaten U.S. allies in Asia.

Trump later retracted that statement.

In August, Trump's former buddy, television host Joe Scarborough revealed that the Republican nominee had asked a foreign policy expert why the United States couldn't use its nuclear weapons.

'Three times he asked at one point if we had them why can't we use them,' Scarborough said on his Morning Joe program.

Trump's campaign smacked down the Scarborough anecdote as a lie.
