As Bob and George discussed, forcing yourself and your desires on other countries is quite different from being available for mutually desired/beneficial engagement. As in all social engagement, becoming completely isolated is not the only way to resolve or dissolve conflict.
I think you are not factoring in how empires work. In an empire, the will of the people becomes secondary to the desires of those with special interests in the FP of the empire. By breaking the US into regions, the feds will no longer have the resources to routinely project force overseas.
Regarding isolationism, I don't see import tariffs and sharp limits on immigration as being harmful. Such a policy works very well for China.
