Trump and Vietnam.

Donald Trump did not avoid killing Vietnamese people in their own country as a matter of principle. He dodged the draft to save his own skin. As Mr. Khan said at the DNC, Donald Trump sacrificed nothing: no arrests for protesting the war, no police clubs on his head trying to stop it.

Plus, like many of America's most prominent warmongers, he is only too happy to play the role of Mr. Tough Guy, a loudmouth bravely boasting about how he is going to send other people's kids to other people's countries to kill other people's kids.

An expression was going around for a number of years after the Vietnam War: everybody did what they did. It means you did what you thought was right: fighting for your country because you believed the politicians' lies or doing what you thought would help to stop the war because you didn't.

Donald Trump never has and never will do what he thinks is right. He does what is good for Donald Trump, no matter who loses money on his crooked schemes or whose kids die so he doesn't have to.
