If I don't respond to you, maybe I'm tired of nonsense. I don't need the last word like some of you do.
The USA's impact on the world has always been roughly equally good and bad.
"The knowledge and prudence of the poor themselves, are absolutely the only means by which any general and permanent improvement in their condition can be effected." - Thomas Malthus
I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality. - MLK
Basically, the history of this country is based on blood, sweat, tears and bigotry....First the native population, then African slavery, the civil war, Jim Crow, leaving nations who needed our help to fend for themselves turning them into enemies. This country has done as lot of wrong both inside and outside. Net negative..
OTOH such unnecessary, drawn out, and divisive wars as vietnam and GW's iraq led to mass corruption and murder of civilians by troops both abroad and at home. Doing nothing during the holocaust also falls under the "what good?" question.
Then there's plenty of up and downs like pushing/forcing global trade but also scumbag bankers creating global economic collapse...twice.
But without comparing, US has done some positive too like at least attempt to establish education system, often leading in medical and other science discoveries, and if you're a fan of democracy it was called the "grand experiment" for a reason.
The concepts of "good" and "bad" are far too subjective to lend themselves to a simple yes/no query. I would also state that the US has done much evil under the false guise of doing something supposedly good.
