And don't tell me it cannot be done, there is no diplomatic treaty allowing to kick members out of NATO. You boycott Turkish staff, you withdraw your staff from their territory and do not allow them onto yours or into NATO installations and headquarters, and you exclude them from military exercises, CCCI networks and intel gathering, and it is done.
It does not matter what the Turkish government would think of this,
we must not care. We really must understand that Turkey now is hostile to what the "West" is.
