Why iran shut the strait of hormuz after decades of holding back?

Iran closed the Strait of Hormuz because it wanted to make things harder for other countries that use that waterway, like a kid blocking a hallway to slow down their friends.

Imagine you're in a big school, and there's one narrow hallway everyone uses to get from class to class. That's the Strait of Hormuz, a tiny, important channel that ships use to move oil around the world. For a long time, Iran didn't block it because they were happy just being part of the game.

But now, Iran wants to show strength and say, “You can’t ignore me anymore!” So they acted like a kid who takes out their biggest backpack and puts it right in the middle of the hallway, that’s closing the strait. It makes ships wait longer, just like your friends would if you blocked the path.

Iran had been holding back for years, but now they're ready to take action. It's like when a kid is quiet for a while, then suddenly shouts, “I’m not going to let you pass!” That’s how iran shut the strait of hormuz, with a little bit of boldness and a lot of real-world power.
