Why people care that two overpaid actors have a pretend feud on camera is beyond me. Trump and Zelensky aren't in charge of anything other than PR. The message is simple, the West lost in Ukraine and now it's time for America to break up with Zelensky.
But just because the US is officially shifting the focus from Russia to Iran, until WW3, it doesn't mean they can let the EU vassal states undo the damage and reconnect with Russia. That's why EU politicians were told to keep antagonizing Russia.
