That was pretty much Lindbergh’s line when he was supporting Hitler.
Not everyone you dislike is Hitler.
That does not invalidate the logic of the position. You are using a typical piece of apriori manipulation,denoting reasoning or knowledge which proceeds from theoretical deduction rather than from observation or experience.
There do appear to be a lot of people for whom all foreign policy questions precede from the dismantling of the Czech state and that all opposing leaders are necessarily a Hitler clone. Neither are really so and this bit of nostalgia as thought is just dishonest attempt to discredit non-interventionism as automatically ‘immoral’.
