With Tweedledum and Tweedledee in charge of our military I don’t think the Russkies need to worry.
The problem with our “military” as you reference is NOT a matter of capability. It is a matter of will.
We “fight” conflicts under the rules of the State Department and left with goals that have little to do with the military.
The core purpose of a military is to impose your will in brutal and overwhelming fashion. Period. It is not to “nation build”, “occupy”, or promote Western values.
It exists to smash our enemies. Our leaders will not allow it to do so.
Just think..... we suffered few casualties in Iraq or Afghanistan until we decided to occupy and impose our values on them. We achieved the initial goals (minus Bin Laden) of smashing them and then it all turned to shit with contractors, occupation, and the money funnel.
What if we had just smashed them, left, and told them to clean it up or we would be back? How many lives would have been saved on both sides? How much wealth would not have been spent? How much better off would we have been?
