I usually hear this what-aboutism argument from the people who benefit from current undemocratic regime.

If another country did/do something wrong, that doesn't justify Iran's actions. everyone is responsible for their own action and the reality is current Iranian regime has killed many thousands of it's own citizens.

Iran shutting the plane down and denying for 3 days is not justifiable by any means.

out of curiosity, what is your opinion on 1500 protesters who died during 2019-2020 protests? https://en.wikipedia.org/wiki/2019%E2%80%932020_Iranian_prot...

should we ignore this too because Israel also killed bunch of people?
