| Obviously. The things the POTUS says, are intended to further the US Government's goals. The actual statements made may be true or false. If POTUS says "We did X because Y", that's no guarantee that Y is the reason that X was done, or even that X was done at all. That just means that POTUS would like people to think that Y was the reason X was done. That Trump is also a serial liar is not actually relevant here, this is true for every President. They make statements in service of their agenda, not in service of the truth. |
Secondly, even if argument could be that 'some other, more credible president would lie' - this actually does not hold up, because nobody could operate in those terms.
The presidents statements in an official context are official, that's it. Except in rare cases.
"He tells people what to do on a whim" and "has longstanding personal beefs and gripes" - that's it.
We don't know what he's going to wake up and tweet tomorrow so all we have are his statements.
Also, I think we give way to much credit to this notion of '4d chess' - he lies in the moment because he can get away with it, not out of some well plotted deception. He's not servicing some complicated scheme - just his gut.
He'll say something else the next day, but for that moment, what he says is policy.
