It's about business. The majority of oil companies that are in oil-rich countries are American companies - keep the foreign oil flowing and keep American oil companies in business.
What does your response have to do with American oil companies not being able to drill in ANWR or off-shore?
(Oh, and without actually looking at the figures - I would imagine that the US does hope to turn a profit from the invasion.
Turn a profit, how exactly?
Oil companies often don't make a profit as it is. Even if Iraq had say 2 trillion dollars worth of oil in her fields, and the Americans somehow managed to gain access to all of that oil (a ridiculous claim that's completely untrue), the oil companies would only see a sliver of that 2 trillion dollars in actual profits.

They are digging in for the long run in Baghdad with, IIRC, what amounts to a whole village for the US embassy.
Embassies usually aren't sources of profit. Since when have they been? The government funds embassies, not the other way around. I'm not even sure what this comment has to do with claiming Iraq was invaded over oil. I assume it was something to pad your post with irrelevancy from our resident spambot.
Whilst some contracts are going to the Chinese - in areas which are quite dangerous - I'd like to see overall how much of the Iraqi wealth is going to the US and US interests vs other countries. Now, that would settle the argument with hard facts.)
Yes, it would be good if you actually looked at the facts. Even going so far as claiming the Chinese companies got oil fields in dangerous areas....such as southern Iraq.
