> I've seen TikTok videos go viral being really critical of the US government including its foreign policy.

I posted an example of a video that is critical of the US government including its foreign policy. This seems like reasonable evidence that one can find videos critical of the US government including its foreign policy on the TikTok platform.

Noteworthy is that TikTok is a distinctly different platform than Twitter in many ways. One might even go so far as to say that it's possible that TikTok may even have the possibility of being a more influential platform than Twitter, particularly for certain demographics such as young people, who often have impressionable minds and openness for new ideological beliefs.

A potential example of the power of ideological beliefs might be observing that intelligent, rational people in a forum will downvote someone who literally provides an example of what someone else asked for. Imagine what sort of mass behavior modification could be achieved with an ongoing campaign designed by people who have a deep understanding of human psychology, leveraging the capabilities of a platform like TikTok that is well proven at propagating memes.
