For a legal scholar you seem to be very flexible with actual legal matters and you do like to draw comparisons between not directly comparable things
Crimea was annexed by Russia in a gross violation of Budapest memorandum form 1994 between Russia, Ukraine, USA, UK, Belarus and Kazakhstan, when Russia attacked its then ally Ukraine back in February 2014 without any casus belli
Golan Heights were annexed by Israel in 1981 after Syria tried to attack and invade Israel twice in 1967 and 1973 and failed miserably. Plus prior to 1967 Syria used Golan Heights as an upper ground to shell entire northern Israel from Haifa to the Sea of Galilee with dozens of Israeli civilians being killed as a result
You don’t get to create a casus belli, start a war, lose it and return to square one once again. That’s not how world and international law work
So no, Crimea and Golan Heights are incomparable
The Golan Heights is Syria.
Crimea is Ukraine.
The U.S. recognizing Israel's illegal annexation of the Golan Heights has the same legal weight as Nicaragua recognizing Russia's illegal annexation of Crimea.
