<< If, like W. Bush and Cheney, he starts a war of opportunity ... >>
Trump is flirting with the idea of nominating John Bolton as the chief under secretary to the Secretary of State.  This is a sure sign that Trump is looking for a place and an excuse to wage war -- that has been John Bolton's main function in government service.  Trump lied (everyone knows that he lied: it's preserved on tape)  when he said that he had opposed the invasion of Iraq.  More important, he lied when he said that he would not lead the United States into another similar war.  Trump’s fragile adolescent male ego requires a war; more than that, he knows that he needs a war to distract the media and the public from the massive transfer of wealth, resources and opportunities from the bottom 98% to the top 2% which will be occurring on his watch.
Reporting today suggests that Bolton may not be nominated, or may not be confirmed if he is nominated. Still, Trump's interest in Bolton tips his hand.
