Not so fast, Kim Jong Un!

North Korea's controversial intercontinental ballistic missile test on Tuesday caught much of the world offguard, and the country's dictator has seemed gleeful about showing up President Donald Trump on America's Independence Day.

There was only one group not surprised: The U.S. military.

A high-ranking senior official told Fox News that U.S. officials watched North Korea prepare and fuel it's first missile the entire time — and chose not to deploy an anti-missile defense system to shoot down the rocket.

In other words, Trump and Defense Secretary Jim "Mad Dog" Mattis were both ahead of the game — but let the test go on to give the military all the information they wanted regarding Kim Jong Un's capabilities.

"Clearly we watch North Korea very closely," Pentagon spokesman Capt. Jeff Davis said in a press briefing. The launch was from an area previously unused by the reclusive communist country, but was caught early in the process by our military.

Conducting the entire process in clear view of American eyes gave the Trump administration precious new information on the status of Kim Jong Un's missile program.

"Given the apparent advance notice enjoyed by U.S. officials, the Pentagon could have decided to try to shoot the ICBM down using the U.S. missile defense shield components in the region," Fox News reported. "But because the missile wasn't a threat to North America, the U.S. declined to attempt to terminate the rocket, which flew 1,700 miles into space and was in flight for 37 minutes."
