My heartfelt sympathy to the MH17 victims and families, but the airplane was flying in the risky warzone. That does not discount the fact that it's an atrocious act by the Russian backed military.

However, to send missile to primary school killing hundreds of school girls on the very first day of the war, if intentionally is just pure evil.

Am I missing something?

The attack on the Iranian primary school (not makeshift sheltered building) is on the very first day of the war, not several weeks, months or years.

Not to downgrade the incident, but the Mariupol incident you mentioned probably happened in 2022 while the all out war started in 2014 [1],[2]. If you can refer and link to the particular incident it'll be helpful for verification.

Propose a nuclear free zone in the Middle East, propose a global nuclear free zone, propose to cooperate with other nuclear powers to disarm.

But that’s apparently not the real concern at all.
