the claim was made that Russia Ukraine war wouldn't have occurred with Trump as President

total bollocks

The bollocks are all yours with claims such as:

Malcolm Turnbull says Donald Trump's 'creepy' embrace of Vladimir Putin a threat to Australian security

Biden is the President NOT Trump, and Sleepy has helped the Ukraine war along very nicely - fact

Anything you say about Trump and the Ukraine war and Putin is just speculation not fact

Who is the bigger dope - Turnbull for saying this, or you for believing it
