Churchill believes that an invasion of British soil is not likely to occur in the near future because the enemy would have to cross the heavily guarded sea to get there. 
In his famous speech, "Their finest hour", given on 1940, Churchill said that for the Germans to cross the English Channel, they would need to have a large armada, that would be "intercepted long before it reaches the coast". There would be many obstacles in the way of an invading Navy, such as minefields, air bombings and the British Navy itself.
