The guarantees given to Poland by Britain and France marked the end of the policy of appeasement. Instituted in the hope of avoiding war, appeasement was the name given to Britain's policy in the 1930s of allowing Hitler to expand German territory unchecked. ... Appeasement was popular for several reasons.

Immediately after Britain and France declared war they didn't really taken the offensive anywhere. It was the beginning of the Sitzkrieg or 'Phony War' during which nothing much happened. It was broken by Germany's invasion of the Low countries and then France itself. Answer Just to add to what Vincent said, they were expecting the war to be similar to the first war with offensive operations being almost impossible against fortified positions. Thus they took up defensive positions in France to await the German attack. their strategy was to build up their strength, let the Germans waste theirs in attacks on the Maginot Line, and then go on the offensive when Germany had been weakened by defeats and a naval blockade.
