President Donald Trump renewed his warning late on April 12 that NATO could face a “very serious examining” after the alliance did not support the United States during its war with Iran.

“I’m very disappointed in NATO,” Trump told reporters as he arrived at Joint Base Andrews in Maryland. “They weren’t there for us. We pay trillions of dollars to NATO, and they weren’t there for us.”
