Lawyer and activist Amal Clooney is to unveil a proposal to put leaders of ISIS on trial for war crimes.

Clooney and U.K. Foreign Secretary Boris Johnson are to reveal a plan on Monday at the U.N. to collect evidence of ISIS’s “abhorrent crimes,” the Independent reports. The object, Clooney explained to NBC Nightly News’ Cynthia McFadden, will be to expose the extremists’ hollow arguments in a court of law. “They are brainwashing people and I think one of the way to take action against that is to expose their brutality and corruption and partly you can do that through trial” she said.

Responding to McFadden’s question as to why ISIS should not be “bombed out existence,” the 38-year-old barrister and wife of actor George Clooney explained that an idea can’t be ended in such a manner. “That in itself can be used as propaganda for further recruitment,” Clooney told McFadden. “ISIS can just be reborn under a different name if you don’t actually change the narrative and change people’s minds.”
