You are truly clueless
Ukraine tried to lift the American ban two days ago. America has made it clear any weapons they supply, can not be used to attack within Russian borders. Google may help if you don't believe the BBC and American press, the Ukrainian media have also reported on the subject. Unless you believe they are all clueless?
The Americans supplied the Afgans with arms to weaken Russia, the same is happening here. Russia is being weakened without the loss of a single American life.
There's a number of top retired American generals who have no trouble accepting the above, again in your opinion they may be clueless and should have their pensions withdrawn?
