What do you know about France? (and the same goes for other people here)
French never committed genocide against jews, the germans did (in in the meanwhile they also murdered 10000's of French), and a few million Jews choose to live in France and the majority of them live well, French jews are represented very well in social, economical and cultural spheres of society.
We had many wars on our soil, and all people over 75 have lived trough one of the worst wars humankind has produced. The US only had one civil war, but that was more than a century and a half ago, but was never invaded or bombed on its territory (except Hawaii). The only wars Americans know are the ones they choose to participate to or the ones they initiated, such as Vietnam or Iraq (indeed horrible wars, did you see the documentory about the central hospital for wounded American soldiers in Baghdad? But for that they have noone to blame but their own leaders they elected)
Talking about genocide, French troops killed many Algerian freedomfighters, but not nearly as many as the number of Vietnamese civilians killed by American occupiers. And talking about genocides, the fate of the indigenous population of the US is not a secret...
