@randahl Another factor in US hinderance in entering the war in Ukraine could be self-serving:
They might simply be holding back, waiting for Ukraine & EU to go into more and more debt.
Once the debt is deep enough, USA could ride in with cheap credit (but with ties) as ”saviour”, binding the Eurozone and Ukraine as clients of American financial institutions for decades, transferring ownership of profits and control without firing a shot, saving their own economy in the process
