Yes but the American people support this action. Enough of this fighting endless wars that have no real benefit for the interests of the USA.
Not really. The US is quite divided and there is no great pacifistic mood at all. And I imagine those who have been fighting there as advisors as well as their families will not be pleased if it turns out like Obama’s premature and idiotic withdrawal from Iraq. Having family who fought over there we felt betrayed by Obama and to this day despise the ‘antiwar’ crowd because it is actually a bunch of socialist ‘right’and socialist ‘left’ and far left communist factions in the US trying to support the Russian, Chinese, North Korean, Cuban, Venezuelan, Iranian and French objective of dethroning the US so one of them can fill the void...a squabble they’ll have later if they can rid themselves of the common threat to their ambitions.
I suspect though, that Trump’s move is not pacifistic but may have to do with increased instability in Iran [and its ally China] as well as a possible angle of making this temporary gesture to prevent US ‘pacifists-in-name-only’ from jumping enthusiastically back onto the Democrat bandwagon before the election. He has employed this sleight of hand before. It may be he is using the Turks to force the squabbling Kurds to unify...with ISIS weakened they will fracture, lacking a common enemy, unless they have a reason to overlook their differences and stick together. In a way it is having a similar effect on a squabbling US congress...all I know is Trump is not always doing what everyone thinks he is doing.
