Trump's fight against the Houthis, by the numbers

Here are some key stats:

• More than 1,000 targets have been hit since mid-March, when Operation Rough Rider kicked off, according to the Pentagon.
• Central Command said it's killed "hundreds of Houthi fighters and numerous Houthi leaders," including drone experts. Al Jazeera reported at least 250 dead.
• The initial weeks of the operation cost nearly $1 billion, according to CNN.
• The Houthis downed several MQ-9 Reaper drones, costing millions of dollars each.
• One F/A-18E Super Hornet being towed on the Harry S. Truman aircraft carrier fell overboard. One sailor was injured.
• There has been only a single public Pentagon briefing on the campaign. That happened more than a month ago.

The bottom line: "Getting to this contentious truce did not come cheap," Behnam Ben Taleblu, an expert at the Foundation for Defense of Democracies, told Axios.

• "By forcing the other side to expend more resources, and even political capital, on defense, Tehran has proved that the Houthis were a low-cost but high-return-on-investment terror option for them starting a decade ago."
