Easy, if they are soooo sure of their prediction of a false flag attack, then they could:

Provide in what way it might happen and when and the why with a carefully explained summary

What puts they have as a result of the expected second order effects from the prediction (Ie, balls deep on Raytheon, etc) as they are super sure of betting against the future of certain companies and betting on favor of the future of others

And what trades have they done to benefit themselves financially in the events of the supposed prediction.

And if the prediction didn’t happen (Ie, the false flag attack) then we can surely say the native language of op is not only poppycock, but with a major on makeup bullshit as well

The failed investments would only compound on the shame for op and hopefully teach them a lesson in predictions
