I think the fact that some conservatives demonize socialism even when they speak of it as the government merely providing essential services goes to show that the Red Scare is alive and well, for the most part. It's not as potent as it was in the '70s or '80s, of course, but it hasn't completely faded yet.
The Red Scare was very different from what
we see today. It was about unconstitutional
persecution & prosecution based upon political
orientation.
The American talk of Chinese world domination and ensuing doom and gloom—under the assumption that China is a "communist state"—is evidence of this even though China, for all of its faults, hasn't waged a fraction as many wars as the US has in the last few decades. It certainly wasn't China that barged into Iraq along with multiple blindly loyal allies and killed half a million people.
China's "communism" isn't really a label about
their economic policies. (Although Xi has stated
he wants to return to the old days of more socialism.)
The label is theirs, & is about political party agendas.
As for US wrongful foreign adventurism, this doesn't
make China any less of a threat to us & other countries.
BTW, China doesn't wage wars so much as it simply
conquers & assimilates countries like Tibet. And
Taiwan on the menu. Our wars are more "wars"
because we go in, we devastate, & then we leave.
(Note that I disapprove of this.)
You might prefer China's behavior to Ameristan's,
but that would be tough to defend, especially their
internal war on Uighurs.
