Well, that's your opinion, and you're entitled to it. I find the idea that the President can do it by simple decree dubious. Even if you could, what's to stop the next President from un-doing it just as easily?
In the first place, as I've told you repeatedly, the president wouldn't need to do a thing if every other officer of government, in each branch, at every level, were simply fulfilling the first reason for the existence of their offices, which is to protect the rights of the people, all the people, beginning with their right to live.
If this were so, as it should be, any president who tried to open the door to the wholesale slaughter of more millions of helpless, innocent human beings would be checked on every front.
That's how our form of government is supposed to work.
