The Panama Canal had cost 400-500 million USD and 25-30k lives to construct, when it opened in 1914.
The Suez Canal cost around 100 million USD and 100-120k lives to build in 1869.
Charging for transit through man-made infrastructure is fundamentally different from charging for passage through a natural international waterway.
So is bombing countries on a whim.
If you want to take the high ground you have to make sure you don't first poison it with your own stupid mistakes. Iran can make a pretty credible play for reparations, and if the belligerents are unable or unwilling to pay up then Iran can selectively blockade the strait for their vessels and cargo. It is one of those little details that was 100% predictable going into this.
* Depose's Saddam government
Accomplished.
* Identify, isolate, and eliminate Iraqi WMDs
Failed. They were never there.
* Find, capture, and drive out terrorists from Iraq
Failed. Iraqi-based terrorism increased in the aftermath.
* Collect intelligence related to terrorist networks, and to "the global network" of WMDs
Failed. North Korea tested its first nuclear weapon in 2006, years after the invasion. The US accuses Iran of trying for them to this day. Chemical weapons were used by ISIS.
* End sanctions
Accomplished.
* Deliver humanitarian support to the Iraqi people, including the displaced
Failed. There were more displaced people due to the war than before and a higher need for humanitarian support which took years to complete.
* Secure Iraq's oil fields and resources, "which belong to the Iraqi people"
Accomplished. Somewhat, US and UK based companies, plus China, now runs a lot of their oil fields. Iraqi GDP per capita is one of the lowest in the region.
* Help the Iraqi people "create conditions for a transition to a representative self-government"
Arguable. Parts of the country want to secede and have armed groups. Representation and turnout is not amazing, but I guess not even in Western countries it is.
The cynical read of this statement (extract resources from the invaded countries in order to enrich the American capital class) is the primary aim for all these conflicts.
