President Donald Trump and his top national security officials spent much of their day in the Netherlands working to rebut an early intelligence report that assessed weekend US strikes against Iranian nuclear facilities did not destroy the core components of the country’s nuclear program and likely only set it back by months.

NATO’s summit in the Netherlands has been described as “transformational” and “historic.” The 32 members of the world’s biggest security organization endorsed a plan to massively ramp up defense spending.

The president headed back to Washington after securing a major policy change he’s pushed for since 2017 as most NATO countries agreed to significantly increase their defense spending.
