> Since when is it OK for governments to sanction people when they are lawfully expressing disagreement with Govt policies or views?

When it stops being a disagreement over policy and becomes a paid job for a foreign government to spread as much malicious FUD as possible.

The former commander of Russian ground forces recently gave a long interview in which he said that the Russian army was on the verge of total collapse in the fall of 2022, when Ukrainian forces were pushing them back during the highly successful Kharkiv counteroffensive. Mearsheimer, Sachs, et al played a vital role in spreading FUD and unfounded fears that led to less military support for Ukraine than was needed. As a result, hundreds of thousands more people are dead than might have been had Ukraine been supported properly.

Mearsheimer alone has done more to deny modern weapons to Ukraine than the entire Russian air force could. In terms of ROI, he has been a spectacularly cost-effective propaganda asset. He has the blood of countless people on his hands and deserves to be hanged. But instead, he will kick the bucket due to natural causes in old age, a luxury not afforded to the children who died in their bedrooms under Russian missile attacks that Mearsheimer twisted himself into a pretzel to enable and justify.
