Relations with China were pretty cosy till they did a 180 around the second Bush administration and started all that Wolf Warrior diplomacy, 9 dotted line stuff, Hongkong crackdowns.......
Regarding Russia, nobody really cared at all till it was absolutely impossible to ignore. Putin seems to think that he needs the west as an enemy to bolster his standing and power. Just remember after starting the full scale invasion he proudly declared "I hope I will now be heard" or something to that effect. In Russian mass media the imperial project has long been clear and accepted.
No, relations with China were warm right up through the end of the Obama administration and into Trump's first term. That's why the first approach China took to the Biden administration was to hope for straightforward normalization of relations.
China started issuing 10-year visas to Americans under Obama. The Wolf Warrior movies, after which the policy is named, started coming out in 2015.
The same is largely true of Russia as well. Far from wanting the US as an enemy, Putin even inquired about joining NATO in the Clinton era. I'm sure there were some snickers about 'he doesn't get it, does he'? In fact the CIA initially felt Putin would be a terrible leader since he'd be unable to reign in Russia which was spiraling into chaos and mass criminality in the 90s. Their foresight there was about as accurate as usual.
The notion that China is somewhat entitled to dominate its neighbors because it had a bad run 1-2 centuries ago is a bit silly.
Same way the Soviets wanted to “join” NATO in the 50s. To effectively castrate it and make it ineffective.
It would have been easier for them to politically and economically dominate Eastern European countries from “within”.
> Hegemony in a nutshell
From Chinese and Russian perspective sure. Especially Russian politicians have seen the entire world through an exceptionally imperialist lens for centuries.
On the other hand the US has probably been the most “benign” hegemony (relative to their power) in history (still a hegemony of course).
When the US was engaged in Afghanistan and Iraq the Bush admin and diplomatic circles floated the idea to get China to take on more responsibility in the South China Sea to help manage those territorial disputes.
After all the US was stretched thin and China had and would gain(ed) so much from the rule based order that surely they would be interested in maintaining the status quo and continue to prosper.
Well, next thing China released a map reaffirming their ridiculous 9 dotted line claims and dashed any hope of a cooperation.
Regarding Russia, people have cared since the Bolshevik Revolution in 1917. The fear of communism and concerns about Russia grew until the red scare in the 1920s, through the cold war, and continues to do this day. There has never been a single point in your life when "nobody really cared at all" about Russia.
America's concerns over Russia died down a lot from what it was after the collapse of the USSR but never really went away. That said, if Putin hadn't been doing his best to fan the flames America would probably still be focused on the middle east as their new favorite boogeyman.
Fear of communism is almost an orthogonal issue, and it has more to do with fear of insurrection and revolution.
