> Does the US needs all that oil?
The USA doesn't need to use the oil for the USA to claim there is either a "national security" or world geopolitical rationale for going to war to "protect" it.
Petrodollar Warfare[1] is a theory that the US can and does attack (or otherwise undermine) any oil producing country that tries to transact its oil in any currency (or commodity) other than USD.
I think this means that someone else tries to ignite a war. Could be similar to the USS Liberty incident, but it all needs an investigation by neutral parties. Does the US needs all that oil?
