John Bolton has been described not so much as “America First” as “Military First”. He is credited as being the chief architect of the Iraq War under the GW Bush administration. He remains bumptiously unapologetic about promoting that war, which was based on lies and resulted in as many as one million deaths.
Bolton relishes in open contempt for the United Nations and international law, viewing both as hampering the United States from using military force whenever and wherever it wants, in pursuit of its geopolitical objectives.
He has stridently called for US military attacks on North Korea and Iran, to instigate regime change.
So, for “mad hatter” Bolton to have the ear of the president in matters of international security is indeed a cause for a foreboding apprehension. Especially given also that President Trump already seems riven with a confused foreign policy and a worrying impetuousness in dealing with the rest of the world.
