The US doesn't need to "side with Iran" on anything: ship captains, owners and insurers are free to gamble their ships and payloads against Iran's resolve and strike capabilities, my assumption is they like to predictability make money, and not losing customer's billion-dollar payloads is part of that.
Having your ship blown up won't guarantee the US will consider the ceasefire violated, history is littered with post-armistice engagements and deaths.
Would you go to your normal job tomorrow if someone who has a history of carrying out threats has threatened to kill you for it?
I can spend 10 minutes looking at demographics and tell you the world is not explainable if the measuring stick is my own risk tolerances.
