for hitting Arab countries in the region, saying the attacks would stop.

Did I miss something, or was this yet another Trump lie?

To neighboring countries for Iran's attacks on them. It was posted on DU and reported in MSM with video.

Ironically Iran was actively launching attacks on Gulf states while their President was apologizing for previous attacks.

The U.S. has started a war with against Iran, a country that supported and sympathized with, the U.S. when the 15 Saudi Arabia scum flew passenger jets into the Twin Towers, Pentagon and PA.

But now, that same Saudi government looks for sympathy from the U.S. after getting whacked by Iran government who objected to the Saudi 9/11 strikes.

And we're talking selling F-35 jets to the Saudis, and we haven't yet interrogated the families and friends of the 15 Saudi terrorist pilots so we can close in on the individuals having to be tried and imprisoned for the 9/11 disaster.

Allegedly secret talks had taken place between Trump and bin Salman recently where bin Salman lobbied for bombing Iran

Or was that yesterday?
