You can get the rules from Hasbro's web site here: http://www.hasbro.com/common/instruct/Conflict.PDF
There are some general rules here:
http://www.boardgamegeek.com/thread/147314
http://www.boardgamegeek.com/thread/69952
both of the pages have general information and some specific rules.
I also found Conflict in a list of game rules for sale on this site, if you want some official ones:

Another option is to buy a copy of the game. I saw one on eBay as I was searching for the rules, so they are still out there.
