I loathe Sean Penn. That said I see nothing in this article that shows him advocating for World War 3.
Sending Jets = WW3, due to blame for providing them and the logistics of which airport they would use would become a legit military target of Russia, even on NATO land.
I liked him as Spicolli. But alas, his career has gone downhill ever since.
He did have a reasonably good part in 'Team America', where he played himself.
He does need to be bitch slapped about 50 times anyway.
Idiot.
