Unfortunately, the US government and Pentagon do work like this. We must stop Putin because if he defeats Ukraine, he'll conquer Europe! Speculative wars are the US' bread and butter.
Democrats would have ensured they had a solid candidate and campaign if they were worried about a fascist takeover. They promoted the Arab-Muslim murderer Dick Cheyne's endorsement and campaigned with Liz Cheyne while funding and aiding a genocide in Palestine, adding an insult to injury.
US foreign policy is fascistic, and the Democrats' immigration policy and two proxy wars proved they weren't unlike the Republicans. They ran a right-wing-light campaign and failed, but it's no skin off their backs; they'll have another run in four years.
