> How does anyone just open a strait that has mines in it in 2 weeks?

The strait has been open for weeks for friendly countries' ships that pay Iran $2M per passage through their "toll booth", an unmined route through Iranian territorial waters.

This ceasefire appears legitimize that situation. If it holds, Iran is about to make huge amounts of money on top of sanctions relief.

The strait is barely mined, at most a few dozen mines were placed. Multiple ships have transited through in Omani waters since the start of the conflict. So far none have been struck by mines.

The threat why boats do not cross are Iranian missiles / drones striking ships attempting to pass thru, without paying a protection fee. It's basically a terrorism protection fee.
