It ended with all ministers thumping the table in support to continue the struggle whatever the cost. After that there was absolutely no support for a deal with Hitler.
But having said that, Churchill probably knew that he only had to hold out for a limited period until his friend Roosevelt brought the US into the war.
Operation Dynamo (Dunkirk evacuation) was between 26 May and 4 Jun 1940. Singapore fell on 15 February 1942 (i.e. over two months after the US had entered the war).

As for the Royal Navy, it need only have been dealt with long enough for a landing force to have established a tête du pont, which could readily have been accomplished if closely coordinated with an airborne landing just prior to an amphibious invasion.
The Germans had committed all their available paratroops (1st parachute division) and airborne troops (22nd air landing division) in the attack on the Low Countries, where they suffered heavy casualties. Their commanders (Student and von Sponeck) were wounded and a number of the trainers from the parachute training school (who had been sent into battle too) were lost as well. The Dutch managed to send 1200 paratroopers and airborne infantrymen as POWs to Britain before the surrender. After the surrender the Germans sent at least a thousand surviving paratroopers to Norway to bolster the German defence of Narvik. More importantly, the Luftwaffe had lost about half of its entire force of transport planes over the Low Countries. These losses could not be replaced in time for an invasion of England in the summer of 1940.
At the same time, as you mentioned, the Kriegsmarine had been weakened by the Norwegian campaign, in which it lost the heavy cruiser Blücher, light cruiser Königsberg and a dozen or so destroyers. Heavy cruisers Lützow and Hipper and battleship Gneisenau were damaged and Prinz Eugen, Bismarck and Tirpitz had not yet been commissioned. The German navy could therefore not have shown up in force for the invasion. Landing craft were in short supply too.
These considerations would have made a German invasion of England in the summer of 1940 a hazardous campaign, but not, I agree, totally impossible.
