Don't know anything about Zelezny, but perhaps more notable is that Trump confirms "Finders Keepers" doctrine for clay:

President Donald J. Trump’s recognition of Israeli sovereignty over the Golan Heights upends a half century of U.S. policy. The strategically important plateau has been widely considered under international law to be occupied territory since its 1967 seizure from Syria. In his proclamation, Trump cited security needs as paramount, though in practice Israeli control has not been challenged for decades. Experts warn the move could weaken international prohibitions on acquiring territory by force.
