President Donald Trump's former National Security Advisor is urging him to launch a pre-emptive military attack on Iran.

Ambassador John Bolton called for a strike one day after Trump tweeted approvingly about the assassination of Iranian scientist Mohsen Fakhrizadeh near Tehran.

Bolton, a neoconservative who is known as a war hawk, accused Iran seeking nuclear weapons for terrorism. However, former CIA Director John Brennan says the assassination itself was "state-sponsored terrorism."

"Iran's terrorist regime is seeking nuclear weapons for terrorist purposes. Faced with such a threat, a pre-emptive strike is fully justified," Bolton posted on Twitter.
