It's definitely not bluster, he fired his Secretary of Defense over his refusal to pull out of the conflict. It's one of the most consequential decisions of his tenure so far.

I'm curious, why do you believe Trump's decision to withdraw from Syria is a good one?

I support the eventual withdrawal from Syria, but packing up now will place a large burden on Kurdish minority groups in the region, who deserve better. It will not be the first time we supported the Kurds while they advanced US goals and then pulled out ASAP.

It also seems the decision was motivated by conversations between Trump and Erdogan, which makes me think the Turkish will resume subjugating Kurds in the region when US exits.

I think we should withdraw by replacing more and more guns-and-boots people with books-hammers-meds people.

Leaving a power vacuum to be filled by Turkey or Russia seems to be the worst option, and imo a betrayal to our Kurdish allies who would not be treated fairly under Turkish or Russian control.

Edit: I really mean this question in good faith. This is my present understanding of the situation, but I do not believe I have the whole picture. I really appreciate the time anyone could take to point out an inconsistency or misunderstanding.

I think a basic problem with your analysis is that there will always be an emotionally compelling reason to commit troops to enterprises like this. We have to support our allies, the Kurds. Saddam Hussein and his sons are cruel dictators. Iranian theocrats are intent on destroying Israel. There are concentration camps in North Korea. Gaddafi is a dictator and sponsor of terrorists. Etcetera.

These reasons aren't wrong, those things are true. The problem is that they lead down a path of interventionism which hasn't worked very well. For example, Iraq. Hussein really was a cruel dictator but by invading and destabilizing the region the conflict killed a million or more people, generated ISIS, and left the area tumultuous.

I also want good things for the people of Syria. I don't think it's fair for them to be ruled by Asad. Where I disagree with people who advocate continued military intervention is that I don't think this is the right way to help them.

I think the right way to help people is by exemplifying the virtues of our system of governance and economics. We should become a country that others want to emulate. We should spread good ideas, like the rule of law, human and civil rights, regulated but mostly free markets, etc. Other countries will desire our prosperity and change of their own accord to become more like us, not because we're pointing guns at them, but because they genuinely want to live the way we've shown is possible.

I see this approach as unraveling the networks of evil in the world. Russia changing to be less of an oligarchy, permit more free press, better cooperation with the world, more Democratic will likely entail less support of Assad.

So much this. The "great" thing about the world being a mostly terrible place, is the government can pick and choose where to intervene for reasons other than helping people. This gives the government some cover because people say "well Hussein is a bad guy" even though we ignore the bad guys in a bunch of other countries out there for completely mysterious reasons.

I think, actually that the region would have had its melt-down one way or the other. The Arab spring would have happened anyway. And he most likely would have swept Hussein away. Vietnam told us, that in the long run, no foreign power projection prevails against local interests aligned with local powers.

And it will happen again, in about 1.5 generations- waving over a region, who will be very much beyond peak oil. Which will have all those in power at that moment, trying to vent the tension the good old European style- by sending those revolutionary's with all the emotional words and no plans on how to make the world a better place into endless ditch wars.

So the board for the great game is been lay out- now the most relevant game piece has to be determined. Who is the Germany of the middle east?

As in a currently disassembled power-house without resources, that reassembled is capable of innovation and thus is a danger for all current major players.
