I would prefer an Isolationist policy for the time being.
We don’t need an isolationist policy. We need a retaliatory policy. A war policy is only right if one has an enemy requiring war and the wherewithal to actually engage in 24/7/364 war with the entire nation’s resources and people focused on bringing an enemy to total submission. (As we do it in our era an “absentee, rotational war” policy is an affront to the morale of any military, and should never again be the policy of this nation. Both Vietnam and the Iraq/Afghanistan duet have proven it unjustifiable.)
A retaliatory/reprisal policy has the US strike quickly, completely, and lethally against any enemy or government that attacks or clearly threatens us.
