Chilean President Gabriel Boric condemns coordinated attack by the United States and Israel against Iran:

"The United States has just announced it bombed nuclear facilities in Iran. Attacking nuclear facilities is prohibited under international law. Chile condemns this U.S. attack.
We will defend respect for international humanitarian law in every forum. Having power does not authorize its use in violation of the rules we have established as humanity. Not even if you are the United States.
We demand and need peace."

What realistic legal actions can be taken against USA/Trump ? Because what he did is against international law.

I hurt myself today
To see if I still feel
I focus on the pain
The only thing that's real
