When can the Republican Party or just conservatives in general switch to being Non-Interventionist?
We've been too far spread for too long, with seemingly no positive outcome. In any case Democrats seem to have proved that they can't fully back out of a territory in about 8 years, so it's self-sustaining anyway.
The best way to stand out seems to admit that we have an internal threat, take care of ourselves, and sell weapons to our allies.
On the selling of weapons; I meant to our 1st world allies who are at or near tactical parity, but may not have the Military industrial complex to keep going indefinitely.
