It comes as Mr Biden is set to allow Ukraine to use long-range missiles to strike deep into Russia for the first time, writes lbc.co.uk.

The move would be a major change in American policy after months of pleas from Ukrainian President Volodymyr Zelensky. But Donald Trump Jr has argued that it could risk starting another world war before his father can return to the White House.

“The Military Industrial Complex seems to want to make sure they get World War 3 going before my father has a chance to create peace and save lives. Gotta lock in those $Trillions. Life be damned!!! Imbeciles!”, - he tweeted.

Ukraine plans to carry out the first long-range attacks in just days, according to Reuters. It is expected to use ATACMS rockets which have a range of up to 300 km in the offensive.
