The US-Iran war is also a battle for the survival of the US dollar!

In "The Real Reason the US Is Attacking Iran," it was mentioned that the main reasons for the US attacking Iran are twofold: one is to control Iran's oil, and the other is to seize the Strait of Hormuz.
It is now very clear that Trump openly stated that he wanted to seize Iran's oil, and the US is now also fighting for control of the Strait of Hormuz.
When an event occurs, its cause is often not singular.
From the perspective of oil capital, it was mentioned in "Once Again Guessing Right, the US Is Indeed Blocking Hormuz!" that the US destabilizes the Middle East, preventing Middle Eastern oil from leaving, so that US-controlled Venezuela's oil can be sold in large quantities.
Today, news reports show that the US is now close to becoming a net oil exporter.
Additionally, from a financial perspective, the US attacking Iran is also a move to prolong the life of the dollar.
Historically, whenever oil-producing countries dared to challenge the dollar, wars almost always ensued.
Saddam wanted to abandon the dollar and settle in euros, which led to the Gulf War and the Iraq War, destroying him completely;
Gaddafi didn't even want to use euros and settled directly in gold, which resulted in Libya being torn apart by the US;
During Maduro's era, Venezuela's oil was not mainly settled in dollars, and then Maduro was arrested;
Russia's move to de-dollarize led to the Russia-Ukraine war.

Today, the situation is similar—when Iran stopped settling in dollars, it seems to confirm the above historical pattern once again.
Amid the wave of de-dollarization, the US dollar's share globally has fallen from over 80% to around 40%, and the share of dollar payments for global oil has dropped from over 90% to about 55%.
The main reasons for the decreasing dollar share are twofold:
First, the US itself is causing trouble by weaponizing the dollar—imposing sanctions, which makes others cautious and leads to currency diversification, reducing the dollar's share;
Second, countries like Russia and Iran are being sanctioned by the US, which forces them to avoid using the dollar, thus decreasing its share.
Second, as other countries' power rises, they naturally adopt their own currencies.
For example, in Russia's trade with certain countries, 99% is settled in their own currencies.
Apart from the fact that the US can't use the dollar everywhere, the rise of major powers reducing dollar usage is also a reason.
As the dollar's global reserve share diminishes, the US dollar's status as the world's reserve currency becomes increasingly precarious, and US dollar hegemony will gradually fade.
The more oil controlled by the US, the greater the dollar's share.
Therefore, when the US targets countries like Venezuela and Iran, besides wanting to control their oil and make money, increasing the global share of petrodollars is also likely a goal.
From this perspective, the US-Iran war is also a battle for the dollar's survival!
