Trump Bashes US-Saudi Relations, Slams NATO Allies

Republican presidential front-runner Donald Trump on Saturday questioned the United States' protective relationship with Saudi Arabia and again accused U.S. allies of not pulling their weight in the NATO military alliance despite mounting bipartisan pressure on Trump to soften his tone.

The billionaire businessman told a campaign rally in Racine, Wisconsin that allies in the North Atlantic Treaty Organization "are not paying their fair share" and called the 28-nation alliance "obsolete."

"Either they pay up, including for past deficiencies, or they have to get out. And if it breaks up NATO, it breaks up NATO," Trump said.

Trump has frequently criticized NATO in recent weeks as the race for the Republican nomination for the Nov. 8 election has heated up.

At a campaign stop in Wausau, Wisconsin on Saturday, Trump expressed concerns over the United States' relationship with oil-rich Saudi Arabia, which Trump accused of not pitching in fair pay for U.S. defense.

"We take care of Saudi Arabia. Now nobody’s going to mess with Saudi Arabia because we’re watching them," he said.

"They’re not paying us a fair price. We’re losing our shirt," he said.

On Friday, Obama cast doubt on Trump's fitness for office after the former reality TV star refused to rule out using nuclear weapons in Europe and said Japan and South Korea might need nuclear arms.

"The person who made the statements doesn't know much about foreign policy or nuclear policy or the Korean Peninsula, or the world generally," Obama said, warning that the world is closely watching the U.S. election rhetoric.

"I've said before that people pay attention to American elections. What we do is really important to the rest of the world,” Obama said.

Trump's comments on NATO have also sent ripples through the Republican Party, which has traditionally promoted a muscular foreign policy.

Tuesday could be a turning point in the Republican nomination race, when Wisconsin hosts its nominating contest. Trump, 69, trails his leading rival, U.S. Senator Ted Cruz, 45, of Texas in the Upper Midwestern state.

A Cruz win would make it harder for Trump to reach the magic number of 1,237 delegates needed to secure the nomination before the Republican national convention in July. The winner will get to claim all of Wisconsin's 42 delegates.
