What's the importance of the US dollar in the world economy? Why?

The US dollar has played a key role in all wars waged by the US in the last 50 years, which were waged in large part to please the Saudis, thanks to the petrodollar agreement signed in 1974 between R. Nixon and King Faisal. Nothing is made of this portentous event in the Western media because if people were aware of it, Westerners would stop supporting US wars and Europeans would exit NATO.
Bloomberg was the only outlet that dared to publish and discuss a copy of the original deal, but there were obviously Saudi influences on the US government that were not mentioned in the agreement.
To answer your question succinctly, the US dollar was the main cause of the horrendous wars in the Middle East over the last 5 decades.
