But Trump doesn't have the mental capacity to understand that:
Iran’s government faced widespread protests in November over rising prices, with many apparently also outraged by Iran’s foreign spending on interventions in Syria, Lebanon, Iraq and other countries while its own economy falters.
More than 300 people were killed in the anti-government protests, according to rights organization Amnesty International. During the violence and in the days that followed, Iranian authorities blocked access to the internet. Soleimani’s killing, however, helped rally the public around the leadership again.
That wasn't the first time Iranian citizens had engaged in widespread protests over economic issues in the last 15-20 years, but it was by far the deadliest. And it may have been the first time foreign interventions by (that's right) Soleimani's Quds Forces have been at the top of their list of complaints. While the government cracked down harshly on these protests, it is somewhere between possible and likely they would have curbed some of those foreign activities to avoid future domestic unrest. Something similar happened with their dockworkers' strike a few years ago. But setting that aside for the moment, it also appears Soleimani was engaged in diplomatic activities on this particular trip, in an effort to ease tensions between Iran and Saudi Arabia:
As part of the incendiary and escalating crisis surrounding the assassination of Qassem Soleimani, there has come an explanation of why the Iranian commander was actually in Baghdad when he was targeted by a US missile strike.
Iraq’s prime minister revealed that he was due to be meeting the Iranian commander to discuss moves being made to ease the confrontation between Shia Iran and Sunni Saudi Arabia – the crux of so much of strife in the Middle East and beyond.
Adil Abdul-Mahdi was quite clear: “I was supposed to meet him in the morning the day he was killed, he came to deliver a message from Iran in response to the message we had delivered from the Saudis to Iran.”
But thanks to Trump, whatever it was they were beginning to talk about went up in flames. It could have been the framework for better relations in the Strait of Hormuz, or some sort of lasting cease-fire in Yemen, but now we'll never know.
