Regardless of what American or Americans are to blame, the situation that's being created should be discussed. Assume the D's are responsible due to them holding the presidency.
It has the effect of putting the Zionist cause in a difficult situation the need to attack Iran, or even just the perceived or manufactured need.
Does Iran have nuclear arms ambitions?
A Zionist state attack on Iran is going to provoke them into a devastating counter attack and that would almost certainly result in the use of nuclear weapons by the Zionist regime.
America has a great incentive to oppose Zionist ambitions, and Biden is most likely being advised on the best course of action.
He's almost certainly not capable of making important decisions by himself. That would be true for America's war against Russia too.
That speaks very loudly for America's position, which would be above Biden's pay grade to resist.
Doddering old fools don't make decisions for America that could lead to such disasterous consequences.
