Iran says it has fixed its air-defense systems after Israel hit them last month. These systems help stop missiles and planes. The attack was part of Israel’s plan to stop Iran from building nuclear weapons.

Now, Iranian regime says it is ready again. Some countries are worried because Iran has a history of helping dangerous groups and speaking against Israel.

Experts warn: just stopping Iran once is not enough. Iran keeps rebuilding. Many say the world must stay alert to keep peace.
