As far as I see it, this message says that America has given up and surrenders it hegemony as long as this administration and the powers that control it are running this doppelganger of what was once a great nation.
It is the international symbol of surrender, but I cannot decide if it is offered by the left as a statement of agenda or as a sarcastic statement of the right that they see us doomed to the submission to global strong men.
or, again, it could be the lame prank of the ill-educated products of our government run schools who thought they were making a statement but couldn't quite understand what they were saying.
