Yes and you would have ruined Saudi Arabia, because you never know what the superpowers are going to do, they will change their stance and relations with Saudi Arabia.
Do you think they will grant you a clear victory ? they will let you both fight each other and buy their weapons, you do not have spare parts for the jets, you want to make the same mistake again..
Khafji was considered part of Kuwait cause that issue was solved by a ( neutral zone ) that shared lands with Kuwait and Saudi arabia, therefor Kuwait considers it part of theirs and Iraq part of its own... though the attack was a mistake for all I know, but irrelevant here.
Financial support is nothing to be proud of, you could be proud of you actually joined and helped, giving oil money is nothing to be proud of.
Besides since all Arabs love Saddam so much, tell me what did he accomplish in all the years that he was in power.
After that I can tell you what mistakes he made, the situation the country turned into is thanks to Saddam and the US, but especially the stupidity of Saddam which allowed the US to do this.
