One big difference between the US and other countries: The US doesn’t look at counterculture as a fundamental threat or challenge to the government. The US citizens actually have freedom. The constitution went so far as to identify the sovereignty of the country with its citizens - thus no royalty.
This might sound quaint to some critical ears of the US, but that is the basis of the law and US systems. The US citizens only need to be reminded of this fact and decide whether they want to reinforce that fact with their personal choices - nonviolent protest, voting, etc.
Edit-That might not seem related to the definition of counterculture, but it absolutely is. The US has a culture of multiculturalism. It has the Amish and lets them largely have their culture within the larger culture. There are many such examples with gradients all over and within the US. Sure, sometimes some of those subcultures get political and exert themselves. But they do it within the peaceful political system as a strong trend.
