Trump reportedly offered Putin a dangerous concession: de jure recognition of Russia’s annexation of Crimea

Former President Donald Trump reportedly offered Vladimir Putin de jure recognition of Russia ’s annexation of Crimea .

Julian Zelizer : The proposal appears to accept the idea that Crimea was once part of Russia and that returning it to Russia would restore historical justice.

Zelizer says Russia 's claim that Crimea is “inherently Russian ” is not grounded in historical truth, ethnic composition or international law.

Putin is beholden to an ideology that demands total victory over Ukraine .

Zelensky has already agreed to a temporary unconditional ceasefire, which is possible.

But the most dangerous part of Trump ’s proposal may not be Crimea at all, but the suggestion that sanctions against Russia should be lifted.
