I doubt very much that you agree with me "for once".
I see American behaviour in this context as normal for powerful nations throughout history and at the present time.
I see the constant emphasis on "democracy and freedom" as sugar-coating for electoral and diplomatic purposes, but like all good sugar-coating it contains more than a grain of truth. The number of democratic states functioning worldwide at the moment is directly attributable to the dominance of the USA since WWII. To say that it is "nothing more than propaganda" is to ignore reality in a way that goes far beyond "sugar coating". It is downright "French".
"Suppression and control of poorer nations" is what powerful nations do. On balance, the way the US has conducted itself in this vein over the past century or so makes just about every other powerful nation in history look really bad.
Apparently, you would like to believe that living in a world dominated by a refreshingly "honest" nation like China would be preferable to living in the world shaped by the American hegemony over the past 6 decades. It isn't just American voters who are gullible.
