I understand that isolationism is historically bad. I understand that we have replaced DIRECT intervention with arming/supporting factions because intervention is wrong... but we seem to be @#$@# no matter what we do. I DO think we need to close our borders and stop all immigration that is not for
1) Science/tech/etc people we need...
2)People who would be killed if they can’t move...
As per the essay, such would make you a “non-interventionist”. However, I agree with your immigration thoughts.
