Harris and Biden no matter what's the rumours biden is good person and want to protect world freedom and american dream values.
If there is possibility of that trump might be elected biden knows trump value is money not really the people.
If trump get in power then there is rumours like trump might put the cryptocurrency owners in usa to pay usa debt atleast those who hold in not self - custody wallets.
Also If trump comes into power then it's a party for all the dictators for all over the world kim will be happy.

But to know all of this Biden might think to start larger scale war to protect freedom and democratic values.
Or Biden knows that some part of the world might fall in the hands of dictators and that's the bigger risks.
There is no good options left Biden might use nuclear weapons.
