France did have a Carrier, Germany built a single Carrier during the war, but did not complete it in time, it was a nice Carrier, easily the equal of the US Fleet Carriers that were built during the war, but even had they completed it in time, the Germans had virtually no airforce left, and what they did have, was certainly not trained in short take-off and landing procedures that would have been required to make full use of the Carrier. There's a funny story regarding the Soviets when they claimed the ship as a prize ship. They loaded it up with everything from that naval yard that wasn't bolted down, and some stuff that was... tried to sail it to Murmansk, and it capsized and sank.
At the onset of the war England had more carriers than the US fleet did, but most of them were aging relics, and when the Japanese hit Singapore, (with a similar attack like the one launched on Pearl) they caught most of the British Carriers there. That was part of the reason that, when the Pearl Harbor raid didn't bag them a single US carrier, Yamamoto knew the war was lost right there. He knew there was no way that the Japanese, even with the Current Carrier superiority, couldn't keep up with US production of flat-tops, the only way they were winning the war was to bag one or two of the three US Pacific Fleet Carriers, and push hard on US interests while they were scrambling to rebuild their Carrier fleet. Other Japanese Admirals, and even the Generals that ran the Army and Marines, thought that the Battleship was still the king of the seas, and were celebrating when almost all the US Battleships were caught and destroyed in the raid, they thought that gave them the Pacific there.
A more interesting thing to note, is the size of the Italian Navy, and a well trained Navy at that, unfortunately, they had a problem getting Oil to run their fleets, so they stayed in port almost the entire war. Had the Italian fleet been fully supplied, the North African Campaign would have ended very differently, because the Italian Navy was large enough, after the French scuttled their fleet at Marseilles, to control the entire Med, and portions of the Atlantic around the Iberian Peninsula. (Basing problems for the Italians would have prevented them from getting too far out into the Atlantic, a side effect of Hitler's Vichy arrangement, Italy needed the fleet base at Marseilles to get anywhere into the Atlantic)
