Wilson confirmed what he had suggested to Wohlthat, including a non-aggression pact and trade negotiations". Most notably, Dirksen has Wilson saying that the proposed Anglo-German non-aggression pact would end the "guarantee" to Poland and the negotiations with the Soviet Union, with the clear implication that Germany would have all of Eastern Europe, in exchange for leaving the British Empire alone. Dirksen also has Wilson saying that the negotiations must be kept secret, as any leak would anger the British people and might even bring down the Chamberlain government, and that Wilson wanted the Anglo-German talks to be held in secret in Switzerland, a statement that does not appear in Wilson's notes of the meeting.Shore, Zachery What Hitler Knew: The Battle for Information in Nazi Foreign Policy, Oxford: Oxford University Press, 2005 page 95 Historians have greatly differed over the version of the Wilson-Dirksen meeting that is correct. The American historian Zachery Shore argued that Dirksen had no reason to fabricate such an offer from Wilson, and Chamberlain, was in fact, seeking to begin secret negotiations for an Anglo-German non-aggression pact in Switzerland that would have seen Britain abandon Poland. By contrast, the British historian D.C. Watt has argued for the veracity of Wilson's notes by arguing that there is no evidence on the British seeking such a pact, which, if signed, would have probably brought down the Chamberlain government. At times, Dirksen reported in his dispatches to Ribbentrop that British public opinion was tired of appeasement and that Britain would go to war if Germany attacked Poland. However, Dirksen noted that the British "guarantee" of Poland issued on 31 March 1939 was only of the independence of Poland, not of its borders, and he believed, based on contacts with British politicians, that another Munich-style deal was possible for the Free City of Danzig to return to Germany. At other times, Dirksen reported to Berlin that Britain would not honour the Anglo-Polish military alliance, and would back down if Germany invaded Poland. In August 1939, Dirksen reported that Chamberlain knew "the social structure of Britain, even the conception of the British Empire, would not survive the chaos of even a victorious war" and so he would abandon his commitments to Poland. Dirksen's messages on Britain's unwillingness to go to war to defend Poland had the effect of convincing Hitler that any German attack on Poland would result only in a German–Polish
