It is asymmetrical warfare. A hundred plus ships went through the straight daily. Attackers only need to occasionally damage a ship to make the crossing look deeply unappealing. No military intervention can promise 100% defense to passing vessels.

The problem is that Iran can defend the strait against the world's most advanced military with drones built with commercial hardware for 30-50K per drone. And that doesn't even take into account escalation, as if the US escalates then Iran will likely start targeting critical infrastructure in the region, making the crisis worse.

The US and Israel are rapidly running out of munitions, while Iran is being resupplied by Russia (https://www.ft.com/content/d5d7291b-8a53-42cd-b10a-4e02fbcf9...) which is much more tooled out for munition production compared to NATO. The US also relies on both rare earths and Chinese supply chain for a lot of its munitions (which it is running low on).

IMO the best option is for Trump to TACO, take the major L, and cede Iran its demands, but this would partially mean an alignment shift from Israel which still feels unthinkable based on the US political realities.

> the price to secure the straight military might look comparatively lower.

The price to secure the straight militarily is a full ground invasion of Iran.

This would be done against a country four times bigger (in population and size) than Iraq, with the kind of terrain that makes Afghanistan look easily accessible, done without the help of a coalition of fools, because this isn't 2003, and nobody in Europe is very eager to send their kids to die for a war that Trump's ego started. His 2025 attempts to 'ingrate' himself with Europe are paying dividends now.

Also, if you think the war is unpopular now (nobody but the 40% of the country that's MAGA-brained supports it - and those guys will support anything), imagine what the popularity would be like with a full mobilization and invasion.

The GOPniks aren't that eager to become a 31-seat party this November.
