Suez crisis for Britain was about UN, US and USSR not approving UK, Israel and France's shenanigans in Egypt and threatened to make shit difficult for them. Brits found this untenable and that made them back off. That was the whole humiliation. UK, the once great empire not being able to act with impunity on the world stage, when a third tier country takes it's strategically important shit, without asking their allies nicely first.

Hormuz is literally US begging for help to win a war that they started, didn't have to start, and now can't win. On the face of it, this is so much worse than Suez.
