Is World War 3 near?

Allowing Ukraine to use Western-supplied long range missiles to target Russia was a rather hostile act by an outgoing U.S. president, adding fuel to the fire as he spends his final days in the White House. Why now and not before? Why did Biden wait until he has one foot out of the door to allow Ukraine to use long-range missiles which can penetrate deep into the Russian homeland? The last act of a poor president who believes that the in-coming Donald Trump will not be so supportive of the war in Ukraine?

Biden and his Democrat Party were well and truly beaten and it would have been better to leave controversial decisions until the new president takes office. After all, he is just keeping the chair warm until January. Rather than trying to pacify the situation there has been an escalation which has put the West on an even more dangerous road in relations with the Russians.
