What Trump is doing and what Obama did to some extent is Retrenchment rather than Isolationism. US is hyper-extended and pulling back is pretty natural reaction after two decades of engagement in Middle East and Afghanistan.
That is not Isolationism, my rule of thumb is when US Navy vacates Diego Garcia (naval base in Indian Ocean), I will consider they are becoming Isolationist until then the talk of Isolationism just hot air.
