As usual, pdq, you are mesmerized by the outer form of the law (official treaties, alliances, U.N. declarations, whatever), and can't seem to see what is actually going on between the lines.

The outer form of the law, when it applies to international relations, is often intended simply to mislead those who are mesemerized by it while the real program goes forward, and the real program was this:

The USA wanted revenge on Iran for the Iran hostage crisis that crippled Jimmy Carter's presidency and humiliated and frustrated America. They wanted to bring down the Iranian regime. They encouraged Saddam Hussein to use Iraq as their instrument to punish Iran. They helped finance his war effort. Their hope was that Saddam's invasion would break the back of the Iranian regime for good, following which the USA could establish a compliant regime in Iran, thus controlling Iranian oil and getting revenge on Iran at the same time.

Saddam did well at first, because he had the intial advantage of surprise and he had better modern weaponry. He did not do well in the long run. The Iranians defeated his invasion. If you call their eventual advances across the border into Iraq "aggression" under that circumstance, then perhaps you would call the Allied invasions of occupied Europe under the Third Reich aggression as well?

Saddam had failed miserably as America's hired gun to punish Iran, but he still was armed to the teeth...and he had nowhere to go...

He had become an embarrassment and a liability at that point. So the next thing to do was wait for Saddam to make his next serious mistake or help him to make it...then pull his teeth. As it turned out, that didn't take too long.

None of this has anything to do with the official out-front propaganda BS, pdq, it has to do with the real strategic moves behind the scenes. Actions speak louder than words.

The USA and UK have been playing a Great Game in the Middle East ever since the end of WWII. That game is aimed at controlling Middle Eastern oil and the marketing of that oil. They used Saddam while it was convenient, they dumped him when it wasn't anymore. They blew it totally when it came to dealing with Iran, though....so Iran is still on the hit list. If there is another war there soon it will be Iran which is targeted. Syria is also on the hit list, but much secondary, I'd say.

The excuse again, just like in Iraq, will be the rumored presence or the rumored danger of WMDs.

It is the excuse most likely to be believed by the American public, despite the fact that Iran and Iraq are both utterly physically and technically incapable of attacking the USA...and they would not attack Israel either unless they had decided on committing national suicide.

Thus, those who already HAVE the WMDs by the hundreds and/or thousands...Israel, the USA, and the UK...pretend to be living in fear of those who don't have them...and who wouldn't even dare use them if they did have them, for the most painfully obvious reasons.

It's ridiculous, but a majority of Americans will probably believe it once again, because you seem inclined to believe anything you are told by Big Brother as long as it places evil somewhere else in the world....and not at home.
