WATCH: Nikki Haley lays down law at UN meeting after Syria strike — and knocks Obama in the process

Nikki Haley, the United States ambassador to the United Nations, laid down the law Saturday during an emergency U.N. Security Council meeting following a U.S. military strike in Syria.

In the process, Haley knocked former President Barack Obama and went after the U.N.

What did she say?

"The time for talk ended last night," Haley said.

"We’re here today because three permanent members of the United Nations Security Council acted. The United Kingdom, France, and the United States acted – not as revenge, not as punishment, not as a symbolic show of force. We acted to deter the future use of chemical weapons by holding the Syrian regime responsible for its atrocities against humanity," she explained.

The former South Carolina governor detailed what the U.S. government knows: that pictures of dead children, victims of a chemical attack, are not "fake news," that Russia is lying about the chemical weapons attack and the U.S. response while being partially culpable for the entire situation.

The time for diplomacy has passed, Haley said.

"We did not give diplomacy just one chance. We gave diplomacy chance after chance. Six times: That’s how many times Russia vetoed Security Council resolutions to address chemical weapons in Syria. Our efforts go back even further," she said.

"With yesterday’s military action, our message was crystal clear. The United States of America will not allow the Assad regime to continue to use chemical weapons," Haley added.

How did she knock Obama?

During her remarks, which lasted more than 7 minutes, Haley explained she spoke to President Donald Trump this morning. During that conversation, Trump vowed the U.S. is prepared to strike Syria again should the Syrian regime launch another chemical weapons attack.

"The United States is locked and loaded. When our president draws a red line, our president enforces the red line," Haley declared.

Of course, Haley's comment was a shot at Obama's infamous Syrian "red line" policy. In 2012, Obama vowed to take action against Syria if they used chemical weapons against its own people. But Obama failed to act in 2013 when Syrian dictator Bashar al-Assad struck his people with chemical weapons.

Syria didn't face consequences for its use of chemical weapons until last year, when Trump struck back at the Assad regime.

What did she say about the UN?

"The Security Council has failed in its duty to hold those who use chemical weapons to account. That failure is largely due to Russian obstruction. We call on Russia to take a hard look at the company it keeps, and live up to its responsibilities as a Permanent Member of the Council and defend the actual principles the United Nations was meant to promote," Haley said.

"We are prepared to sustain this pressure, if the Syrian regime is foolish enough to test our will," she added.
