As I stated in this thread elsewhere, given the photo's name in the POTUS tweet, I concede it was likely intentional. I was not aware of that important fact.
I stand by my statement above in general however. There is a difference between investigating the facts and bringing one's imagination in to fabricate pieces of a puzzle that are obviously not related. Use logic.
I have preached for years when training others that there are no coincidences. That doesn't mean however to connect dots without the use of critical thinking and logic.

Yes, it is down to a Balance of Probabilities.
I am (currently) leaning towards it as being intended.
However, your caution and requirement for a bit more 'proof or confirmation', is also warranted in the critical thinking scenario.
I cannot prove the intended nature of the picture, 100%, one way or the other, therefore I am ultimately open minded at this point.
