The Allied demand of both these states to surrender unconditionally made surrender less palatable than might have otherwise been the case. There is no room whatever for negiotiation. Hindsight is a wonderful thing to behold......
Germany and Japan fought on for many reasons, many fought for duty, many fought to hide their crimes, many fought fanatically out of loyalty to the respective leaders of those countries.
Germany especially fought fanatically because of Goebbels Propaganda of what would happen to Germany if they surrendered, the conduct of the Red Army when it reached German soil somewhat vindicated this propaganda, Also,Nazi Germany was absolutist, anybody even suspected of cowardice or desertion, or speaking out against the regime or even anybody who muttered the word surrender, were brutally put down.
In World War 2; The United States, England, and China had given an ultimatum to Japan stating that they surrender or face "prompt and utter destruction". This was called the Potsdam Declaration. When the declaration was refused, president Truman ordered the bombing of Hiroshima and [3 days later] Nagasaki.

The drafting of the Potsdam Declaration in July 1945 was primarily prompted by the Allied leaders' desire to establish the post-war order in Europe and to outline terms for Japan's surrender in World War II. The successful testing of the atomic bomb by the United States in early July further intensified the urgency to communicate clear terms to Japan, signaling the potential for devastating consequences if they refused to comply. Additionally, the ongoing war in the Pacific and the Allies' aim to prevent further loss of life contributed to the declaration's formulation.
The New Netherland governor that refused to surrender to England was Peter Stuyvesant. He refused to surrender because of an issue over territorial rights between the Dutch and English settlements in the New World.

Germany could have refused to back Austria on the grounds that the ultimatum to Serbia was too harsh. ;)

Has refused, has forbidden, has refused
The final demand is called an "Ultimatum" which is Latin for "the last one", that is a demand. If the ultimatum is refused or ignored a state of war is declared and war commences. This is the correct and legal procedure to declare war.
