NOTE: I for one do not believe that our country’s troops are “losers and suckers”. But Donald Trump does! He has explicitly stated these beliefs, according to several sources who heard it with their own ears.
As far as I know, Trump has not (at the time of this writing) explicitly told our troops that they must follow illegal orders. Nevertheless, he went into a rage when six veterans distributed a message on video in which they reminded the troops that they should not follow illegal orders. He called for those veterans to be prosecuted!
Therefore, Trump’s implicit message to our troops is that they must follow all orders, including illegal ones.
