I read the Kellogg (America First Policy Institute) piece on the Ukraine-Russia war. Here are the broad planks of the peace plan (on page 16 if you want to skip ahead):
A cease-fire and negotiated settlement of the Ukraine conflict.
1. The United States would continue to arm Ukraine and strengthen its defenses to ensure Russia will make no further advances and will not attack again after a cease-fire or peace agreement. Future American military aid, however, will require Ukraine to participate in peace talks with Russia.
2. Put off NATO membership for Ukraine.
3. In exchange for abiding by a cease-fire, a demilitarized zone, and participating in peace talks, Russia could be offered some limited sanctions relief.
4. Ukraine would not be asked to relinquish the goal of regaining all its territory, but it would agree to use diplomacy, not force, with the understanding that this would require a future diplomatic breakthrough which probably will not occur before Putin leaves office.
5. Call for placing levies on Russian energy sales to pay for Ukrainian reconstruction.
By naming Kellogg as the US envoy, I suspect that these are the broad outlines of the peace the US will try to negotiate. It is not an ethical peace settlement but one of the hallmarks of political realism in international affairs is focusing on national interests not what is "right." This is a peace based on realism.
