How did various countries look at Norway with covetousness during World War II?

During World War II, Norway was a neutral country. But the warring countries did not ignore its existence because of this. Germany is even more eyeing it and has long had ambitions to invade and occupy it. The reason is self-evident: Norway is located in Northern Europe and has important strategic significance for Britain, France, Germany and Japan. If Germany and Japan control Norway, the blockade between Britain and France on the German and Japanese navies will be broken, and the German and Japanese fleets will be able to enter the North Sea and the Atlantic Ocean unimpeded. Once Germany succeeds, the British navy will be controlled by Germany and Japan, and its homeland will also be seriously threatened. Germany, which is determined to dominate, will certainly not give up this piece of fat. It will try every means to make Norway its own. Hitler knew very well that Britain and France would never sit idly by and ignore Norway. However, he did not want to engage in a large-scale battle with Britain and France at sea, so he decided to use the method of joining forces with the army and aviation, and let the navy only be responsible for the transportation and escort of the landing troops. However, the war situation quickly reversed Hitler's arrogant personal will. He did not want to fight a naval battle, but the naval battle insisted on insisting on Germany. As a result, the Norwegian waters turned into a sea of ??blood and fire under the power of the German army.
