President Trump, after warning three days ago that Iran would pay "a very BIG PRICE," authorized a drone strike at Baghdad International Airport that killed Iran's top general and second most powerful official, Qasem Soleimani.

Why it matters: Soleimani had cost hundreds of American lives and was among the Middle East's most feared powers. But Iran seems certain to respond, potentially further destabilizing the world's most volatile region.

  • "In killing General Soleimani," the N.Y. Times reports, "Trump took an action that Presidents George W. Bush and Barack Obama had rejected, fearing it would lead to war between the United States and Iran."
  • From the Pentagon's statement: "At the direction of the President, the U.S. military has taken decisive defensive action to protect U.S. personnel abroad by killing Qasem Soleimani, the head of the Islamic Revolutionary Guard Corps-Quds Force, a U.S.-designated Foreign Terrorist Organization."

Behind the scenes: A source in close contact with Trump administration senior national security officials tells Axios that one scenario they are especially concerned about — and have been prepared for — is Iran launching cyberattacks.

  • That's the most likely way that Iran could retaliate stateside.

The big picture: The president who wanted to bring home the troops is now engaged in the most intense conflict with Iran in recent history.

  • So much has changed — and so fast.
  • A few months ago, Trump was musing about bringing U.S. troops home from the Middle East, and to let others fight it out in the sand.
  • Now, he’s adding forces, and they’re necessarily on a war footing.

Between the lines: Trump now has to prepare for an extreme backlash from Iran — and likely intensified attacks on U.S. forces in the Middle East, and anywhere else within Iran’s planning reach.

It also means possible retaliation against U.S. allies, especially Israel, writes Axios contributor Barak Ravid.

  • Prime Minister Benjamin Netanyahu cut short a trip to Greece to return to Israel to monitor the situation.
  • It is still unclear if the U.S. gave Israel any heads up before the strike on Soleimani.
  • Israeli officials tell Ravid that Israel doesn’t know if and how Iran is going to retaliate — but, right now, the decision is to keep a low profile and not get involved in the ongoing tensions in Iraq.

Risk of world war ... CFR President Richard Haass tweets: "Make no mistake: any war with Iran will not look like the 1990 Gulf war or the 2003 Iraq wars."

  • "It will be fought throughout the region w a wide range of tools vs a wide range of civilian, economic, & military targets. The region (and possibly the world) will be the battlefield."

The bottom line: Modern wars are fought mostly with the most expensive, most difficult to recruit, train and retain: special forces.

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.

In her first sit-down interview since being named Joe Biden's running mate, Sen. Kamala Harris talked about what she'll do to fight for women if elected VP, and how the Democrats are thinking about voter turnout strategies ahead of November.

What they're saying: "In a Biden-Harris administration women are going to be a priority, understanding that women have many priorities and all of them must be acknowledged," Harris told The 19th*'s Errin Haines-Whack.
