Russia and China aren’t afraid of American bluster as they know that the USA lacks the power to topple them. Anglos are gibbering juvenile brats forever boasting of how strong they are and how powerful their “secret weapons” are. Russia and China know that’s windy bullshit. Why? The last time that the USA faced peer opponents was in Korea… when it faced the USSR and China, who beat the USA. The American aim was to conquer the Korean Peninsula in its entirety… they failed. The Sov and Chinese aim was to preserve the status quo ante of the DPRK… they succeeded. The USA is taking on the same foes who beat the shit out of them the last time around. Ike ended the war as he saw no point in it (he didn’t threaten anyone with nuclear weapons… he wasn’t an ignorant dunderhead like Chilly Hilly or Trump the Chump). It was expense and death for no good end… so he had the creds to end the war (as a successful World War II general, he could face down the Republican droolers in Congress).
Russia and China are ready to open up another can o’ whup-ass on America… they aren’t afraid. They’re not anxious to go to war… unlike the hubristical Yanks, they had serious wars on their national territories in the 20th century and know the true cost of war. However, they’re not afraid…
