Or were these merely political machinations, designed to disingenuously cast blame while simultaneously justifying a wanton neglect of necessary responsibilities by numerous governments across the globe?
It doesn't matter what the political motivation for questioning is. Specifically, it doesn't affect whether any accusation is plausible or true, or to what extent.

You should really decide whether you want to criticize people for using fallacies, or whether you want to use them yourself. Or, again, at least put more space between the two.
