It's a huge mistake to attempt to build on the fantasy that Trump's "peace plan" is going to result in the need for European "peacekeepers".
Trump's "peace plan" is a red herring, a doublecross to help the Russians win. Forget it.
Instead, make a plan for how to support Ukraine once Trump pulls US aid and lifts the economic sanctions. The Russian Terrorist State will keep fighting.
There's never going to be a need for "peacekeepers", if Trump gets his way Ukraine will become part of Russia.
