Yeah, I can't get on board with blaming the shootdown on Trump. Iran's leaders should have put their airports, airlines, and air defense systems on an alert footing and made damn sure this didn't happen while they were firing missiles at our bases. While this event is part of the overall cycle of escalation, it's Iran's responsibility to conduct their retaliation and associated air defense operations without shooting down civilians in their own airspace. Remember when the US Navy shot down the Iranian airliner in the 80s? You can't blame that on the (then) Ayatollah, even though it was his escalation of tensions in the Gulf that led to our ship being on high alert. We apologized for that, and Iran should take responsibility for this event.
It's one thing to say it's a tragic consequence of the ongoing bellicosity between Trump and the Ayatollah, which it was, and another thing to say it was Trump's fault.
Would they have been shooting those rockets if not for Trump's murdering of Soliemani?
Remember, they hadn't used ballistic missiles like that shot towards Iraq in many years.
