At the same time, he also actively tried to win new allies. Germany is a terrible enemy, so new allies must have the strength equal to or more than Germany. At that time, only two countries with such conditions did not participate in the war, namely the Soviet Union and the United States. Churchill's attention turned to these two countries. He continued to maintain and strengthen his private correspondence with President Roosevelt, discussing the most important issues of Anglo-American relations and the world situation. Churchill still signed the letter "former naval personnel". He likes to play sweet words, even in wartime. He always gives various codes to various meetings and activities.
Churchill actively tried to convince Roosevelt that the victory of Britain would benefit the United States, while the victory of Germany would bring misfortune and disaster to the United States. He tried every means to encourage the United States to participate in the war against Germany. He finally negotiated with Roosevelt, and Britain leased the base in the West Indies in exchange for 50 old destroyers in the United States. The deal is not so much to supplement the British navy as to push the United States to make great progress in the war. Meanwhile. The moral and material assistance (providing all kinds of weapons) that the United States gave Britain in the second half of 1940 and the first half of194 was a strong support for Britain in difficult times.
On May 22nd, Churchill flew to Paris to attend the meeting of the Supreme Military Commission. I also met Wei Gang at the French headquarters in Wansen Castle, and he gave me the impression that he was "firm, decisive and surprisingly active". After consulting with France, Churchill agreed to the plan of joining the northern and southern armies of Wei Gang and flew back to London the next day.
