If Trumps beats the judges on legal immigration, avoids war with Russia, and builds the wall, he is what we thought he was. Hail Trump, God Emperor. Those three items amount to making war on the deep state and winning. Missiling Syria is deeply worrying, but it is far too soon to count him out on what really matters.
And to that excellent post by Heartiste, Minion of Satan, I will add this. In chess, you can see the moves the master makes. When Trump moves, you frequently cannot see him move. Even when his move is public, a fashion statement or a tweet, it is often at a level that you cannot see what he is up to except in retrospect. He is playing a different game to the game his enemies think he is playing. Therefore, while we should take seriously the likelihood that Trump will double cross his loyalists for the praise and flattery of his enemies, we should take considerably less seriously any theory that supposes he is doing something stupid. Which is more likely? That you are smarter than Trump and know more than he does, or that Trump has an ace up his sleeve and a Smith and Wesson in his pocket?
Making warlike moves on Syria is a strategic retreat under fire, never a good sign. The merely temporary government, Trump is retreating under fire from the permanent government. But is is not over till it is over, and now that Gorsuch is in, Trump is free to move on lowering the status of judges, preparatory to going Jackson on them. That is bigger than Syria, though not so big as war with Russia. If Trump gets legal immigration of Muslims severely slowed, avoids war with Russia and avoids installing the head choppers in charge of Syria, the attack on Syria will not have mattered.
