Trump says he will terminate the DACA Program. This will satisfy his xenophobic base. On the other hand he lets moderate Republicans off the hook by a six-month delay. This gives Congress time to pass legislation to overturn Trumps “stated intension.” And so when Congress fixes the DACA mess in favor of the “Dreamers,” he can say to his base that letting in the undocumented is all Congress’ fault.
Of course after he is impeached and then Robert Mueller drops a ton of criminal charges on him from treason to obstruction of justice, which he has already openly confessed to in a public television interview, to money laundering, which the best IRS investigators are feverishly uncovering as I write, his DACA decree will be purely academic.
