In January 1939, Daladier let the "Deuxième Bureau" manufacture the "Dutch War Scare". French intelligence fed misinformation to MI6 that Germany was about to invade the Netherlands with the aim of using Dutch air fields to launch a bombing campaign to raze British cities to the ground. As France was the only nation in Western Europe with an army strong enough to save the Netherlands, the "Dutch War Scare" led the British to make anxious inquiries in Paris to ask the French to intervene if the Netherlands were indeed invaded. In response, Daladier stated that if the British wanted the French to do something for their security, it was only fair for the British do something for French security. On 6 February 1939, Chamberlain, in a speech to the House of Commons, finally made the "continental commitment" as he told the House: "The solidarity that unites France and Britain is such that any threat to the vital interests of France must bring about the co-operation of Great Britain". On 13 February 1939, staff talks between the British Imperial General Staff and the French General Staff were opened.
