Why was the the kindertransport allowed to operate?

The Kindertransport was allowed to operate primarily due to the efforts of Jewish organizations and sympathetic individuals who advocated for the rescue of Jewish children from Nazi-occupied territories. The British government, facing public pressure and humanitarian concerns, permitted the transport of unaccompanied Jewish children to the UK, under the condition that they would be cared for by foster families or placed in hostels. This initiative aimed to save vulnerable children from the escalating dangers of the Holocaust, while Britain sought to maintain a cautious stance regarding broader Immigration policies and the refugee crisis.
