You think Iran is following rules? The whole shit started precisely because Iran does not follow the rules. I am pretty surprised blame here is being rolled on US, when Iran is clearly responsible with their audacious crap they pulled out with that embassy attack.
Besides, as for following rules, didn't they just kill 1k protesters in a matter of days to make sure their regime survives? Much of the bullshit going on in ME is Iran's doing, Iran's money and Iran's planning - Yemen War, Lebanon, Gaza, Syria - everything touched by Iran.
That's following rules? They literally put the whole thing aflame and Suleimani was the spearhead figure of these efforts. He should have been dealt with 10 years ago, that would have saved tens thousands of lives in Yemen alone.
I understand people here have this total irrational hard-on about Trump demonizing him at every single step, but in your almost religious zeal you are going as far as painting Iran as some sort of innocent victim there to the point of siding with Iran. Just stop there. In between US with Trump and Iran with Khamenei - Iran is WAY worse.
