I see this Tweet as more evidence of forward thinking and innovation in language.
I remember Mr Bush had similar phraseology, and his neologisms, regularly introduced, entered the language and became a part of our everyday speech. It is a hallmark of many Republican Presidents that they advance mankind in so many ways.
There has been, for too long, a convention that relative adjectivals should be close to the noun clause they modify
"They should be focused on the much bigger things we are doing, (of which the Moon is a part) including Mars, Defense and Science!"
But this is now so passé! Thank you Mr Trump for once again improving our lives with you simple insights.
