This could get messy.  Trump has shown he has no skills whatsoever in governing so getting involved in a war is going to be a fiasco.

People have some kind of idea that business is more efficient than government.  It is not.   Government is generally much more transparent.  You can not hide big things.   Some company blows 200 million on a failed software project, no one ones.  If they do they have no skin in the game so they just blow it off.   It happens all the time.  Businesses are  not necessarily efficient.  The do however mark up 50 to 100%.   You can have a lot of mistakes and still make money with a 100% mark up.

Government is not a business.  It should not and can not be run like one.   Government should be efficient but generally is found to not be.     People mistakenly then say it should be run like a business.  They are wrong.
