President Joe Biden on Tuesday criticized former President Donald Trump’s comments that he would “encourage” Russia to “do whatever it wants” to “rogue” NATO-aligned countries, calling them “shocking” and “un-American.” “

“The former president has sent a dangerous and shockingly un-American signal to the world,” Biden said in a speech at the White House.

Trump made the comments over the weekend, saying he would not protect a NATO nation that did not contribute sufficient defense funds. Trump’s comments echo his long-standing criticism of the role the United States plays in providing security to other countries, including its key allies.

“If you don’t pay your bills, you don’t get protection. It’s very simple,” Trump said at a campaign event in Conway, South Carolina. “Hundreds of billions of dollars came to NATO and that’s why they have money.”

Biden said there is a “sacred commitment” between NATO countries.

“When America gives its word, it means something. When we make a commitment, we keep it. And NATO is a sacred commitment. Donald Trump sees this as a burden,” Biden said.

Biden said Trump’s comments resonated around the world.

“The whole world heard it. The worst thing is that he means it,” Biden said.

“No other president in our history has bowed down to a Russian dictator. Let me say this as clearly as I can: I will never do it. For God’s sake, it is foolish, shameful and dangerous.”

Trump doubled down on his message to NATO in a social media post on Monday.

“YOU MUST PAY,” wrote the former president.

Trump claimed he had previously made NATO “strong” by telling them to “pay up” or risk losing American protection.

“When I told the 20 countries that were not paying their fair share that they had to PAY, and told them that without doing so they would have no US military protection, the money came,” Trump wrote.

Some of Trump’s closest allies have defended his comments about NATO.

Sen. Tommy Tuberville, R-Alabama, told ABC News on Monday that he supports him “100%” in his effort to get NATO countries to pay more money for their self-defense. Sen. Roger Marshall, R-Kan., said allied nations concerned about Trump’s comments need to “get over it.”
