Edwin Black quotes:

In London, almost all Jewish shops in the Whitechapel district were displaying placards denying entry to German salesmen and affirming their anti-Nazi boycott. Teenagers patrolled the streets distributing handbills asking shoppers to boycott German goods.....

When the Reich could no longer pay its obligations, Germany would go bankrupt.

Fifty-thousand were gathered (March,27th,1933) in and around Madison Square Garden, supportive rallies were at that moment waiting in Chicago, Washington, San Francisco, Houston, and about seven other American cities. At each supportive rally, thousands huddled around loudspeakers waiting for the Garden event, which would be broadcast live via radio to 200 additional cities across the country. At least 1 million Jews were participating nationwide. Perhaps another million Americans of non-Jewish descent heritage stood with them.
