The only difference is, is that before him we had "Iraq has weapons for mass destruction! we must attack them, before they attack us, we're in danger!", and now there's "we're going in and we're taking the oil!".
So from "we can do whatever we want if we lie" turned into "we can do whatever we want", not really relevant to all the people killed.
But hey, some americans would say that "It's worth it" - https://www.youtube.com/watch?v=nP_VnVlFhXU
“Other people did it too” is not an excuse for immoral behavior.
I think the parent and I basically agree.
Trump attacked quite a few countries in his first term, even killed the Iranian general (Soleimani), and you guys reelected him after all that. You guys clearly weren't bothered by that enough to vote for someone else.
If nothing else, Iran has learned that they really need those nukes, because you guys will never leave them at peace otherwise.
