What did he feel was the reaction in czechoslovakia and in the rest of europe?

Czechoslovakia as well as the rest of Europe was disappointed by the treaty as the Germans acquired their territories.  This was Treaty of Appeasement.  Both Britain and France hoped that by giving in to Germany’s demands gave the Germans what they wanted.  Still, German continued her path and that led to World War II.

hello!

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".

hope this
