In contract Law, in Treaties, in business and personal negotiations and arrangements, "quid pro quo, is the basis.
"Something for Something."
To be so biased and naive, to think the President of the US should NOT utilize that concept, is beyond ridicuous.
Such a childish position, would exist in the mind of Greta, AOC, SJW yutes, democrat/socialists, social workers, TDS sufferers, etc.
