Why on earth else would they want to?.... remember this was after Ukraine lost Crimea... and remember when Trump was impeached for a phone call to Ukraine?... that is why Trump could not make that deal in 2018.... or he would have...
Biden had four years to make the deal but all he wanted was an army to try and kill Putin.... and so he let Putin attack and kill civilians because he knew it would start an all out war.... then he started sending money and weapons without a vote of the American people or congress....
And that's your man right?....
