How can you have the U.S. remain isolationist to modern day? How would the world be different? Who would be the worlds superpower? Would the U.S. be better than it is in OTL or worse? Would the rest of the world be better off or not?
Would the rest of the world be better off or not?
Depends on if you include "Kurd" in your definition of "Iraqi", I guess.This question is quite interesting. I'd say, probably not, albeit an Iraqi would probably see this point differently.
economic isolation isn't really possible, but you could have political isolationism for a lot longer. It could start with no SAW/expansion into the Pacific beyond Hawaii... without that, you'd have no US presence in the Phillipines, and no reason to clash with Japan. Preventing WW1 is fairly easy, have Germany make the decision to not attack US ships. Without a US entry in WW1, the incentive to do so in WW2 is practically nil, provided Hitler decides not to declare war on the USA first. However, if there is still a rise of the USSR, it gets harder for the USA to stay isolationist... plus, the USA is going to get dragged into the world whether it wants to be or not, with the increasing reliance on foreign oil and minerals...

Iraq wouldn't be just "Iraq like it was in 2002," America's influence in the Middle East ramped up significantly after WWII, and the country was very influenced by the Cold War.
That is true.
With an Isolationist America, it might be an Ottoman province to this day, though this does not strikes me as a very likely outcome.
