Walking through a crowd of children at the White House Easter Egg Roll, President Trump had a two-word message for North Korea.

“Gotta behave,” said the president.

Vice President Mike Pence took the warning to the region, speaking after a visit to the demilitarized zone separating North and South Korea.

“The era of strategic patience is over. President Trump has made it clear that the patience of the United States and our allies in this region has run out,” said Pence.

The regime attempted a missile launch Sunday but it exploded seconds after liftoff.

The White House is working with China with the hope North Korea will listen to its biggest trading partner but the Trump administration has also made clear all options are on the table.

“A nuclear capable North Korea is not in anybody’s interest and were are going to continue to work with the Chinese on this case,” said White House Press Secretary Sean Spicer.

North Korea insists its weapons program is for self-defense and the Deputy U.N. Ambassador Kim In Ryong promised a tough response to U.S. provocation.

“The DPRK is ready to react to any mode of war desired by the Americans,” said In Ryong.

Dictator Kim Jong Un staged a massive show of force over the weekend with a military parade marking the birth of the country’s founder. The North Korean government said more frequent missile tests are coming.

President Trump’s deputy national security would not say if the U.S. had sabotaged North Korea’s attempted missile launch this weekend. Back in 2014, former President Barack Obama ordered increased cyber and electronic strikes against the North’s missile program.
