Regardless it’s the truth Joe Biden lives in a delusion (and in Joe Biden’s case delusion is not an empty expression) that he is FDR and Putin is Hitler and G-d knows who all gets killed in the end because of that.
And let’s forget other deluded people like Lindsey Graham and Mike Pence.
The Biden-FDR part is not in play. FDR and the rest of the world did nothing for years while Hitler directed Germany to ignore the restraints placed on it as a result of WWI (apart from preparing domestically for WWII, that is). No action was taken with regard to specifically restraining Hitler's agenda prior to the opening days of the war.
While the circumstances then are a bit different than those now, the action that was indicated then is almost certainly the action that would be warranted today.
Any other action, such as the cluster bombs Biden's handlers have introduced, will be misdirected, ineffective and even counterproductive. Counterproductive in a way similar to defunding local police departments in order to correct LEO behavior perceived to be inappropriate.
