That's basically my point. Ultimate responsibility lies with those who decided to fire a missile at a civilian airliner without doing any due diligence or applying common sense, not those who "created tension" or whatever you want to claim the US did in that situation.
I was assuming you were referring to the Ukrainian airliner shot down by Iran in the aftermath of the Suliemani killing, which is an actual example and not a hypothetical one.
It is. It's ridiculous when Israel hits aid workers with missiles and rockets, it's crazy when people wearing press jackets are killed even after communicating their position directly to military command and control. It's ridiculous when children die early, gruesome deaths because they sat next to a bad man with a pager at a Lebanese grocery store.
It's not the 1950s anymore, accountable nations are expected on the international stage to understand what exactly they are shooting at. Israel is under much closer scrutiny than Russia because they represent modernized doctrine and should be using their technological superiority to enable more targeted strikes rather than more indiscriminate ones. Modern Russian warfighting tactics have been under serious scrutiny since the Afghan retreat, then again in the Gulf War, and then again now during the retreat from Syria.
The only "clean" war Russia fought in recent years was Crimea, which was "won" by lying to the international community and breaking their trust forever. As evidenced by Ukraine, today's Russian republic cannot win a war with tactical prowess alone. The "special military operation" has devolved into IRBM fearmongering and rattling the nuclear sabre - Putin knows he's not the president of a world superpower anymore, he's a Tesco-branded Kim Jong-Un.
