"Hypothetically, would you give Trump praise if this entire episode leads to a real withdrawal of US troops in the Middle East?"
Absolutely!
If he finds it in his wisdom to realize true stability in the region requires the absence of the US military, I would argue he has earned the Nobel Peace Prize, unlike Obama.
Trump merely SAID he was withdrawing from Syria, and the anti-Trumpers, in particular every Democrat in Congress, lost their freaking minds.
Imagine if he gave you what you wanted -- a complete withdrawal of US forces in that region. The backlash he'd be subjected to would be no less than the demonization he faced this week. He's already being impeached for slow-rolling aid to Ukraine.]
Although he is gullible and susceptible enough to be flattered to making decisions contrary to his own better judgement, to Trump's credit, he is not a true Neocon or imperialist, but a businessman who only seeks the best business deals for the US. Unfortunately, he is surrounded by the "Deep State", Neocons, imperialist, etc., who, as late Senator McCain used to sing, "Bomb, bomb, bomb; bomb, bomb Iran,", which makes it harder for him to MAGA by returning America to the republic it once was and not the empire that it is in denial.
