The prosecution had clear evidence of motivation (they printed thousands of leaflets, distributing them to many cities in the southern half of Germany) and also evidence of attempts at sabotage - one of their leaflets promoted sabotage of the war effort and institutions, even charities IIRC. Reading the court judgement, it is clear that the court took this matter very seriously. Why fight your nations' enemies on the battlefield, but not fight those who are trying to destroy your country's ability to defend itself from the inside?
Don't get me wrong, it's sad that a couple of young, intelligent university students were brought to such an end. However, there are several good justifications for what the German government eventually decided to do with them.
Iraq and Vietnam aren't great comparisons because in neither situation was the US faced with a destruction or near-desutrction of its country. Millions of Germans were burned alive, raped, expelled, shot, frozen etc. by the very same people the White Rose said the Germans should surrender to. Only the incredible work of the Germans who put one brick on top of another because noone else would do it for them means that Germany still exists as a country today.

at present in investigative custody, regarding rendering aid to the enemy, inter alia, the People's Court, first Senate, pursuant to the trial held on April 19, 1943, in which the officers were:
President of the People's Court Dr. Freisler, Presiding, Director of the Regional (Bavarian) Judiciary Stier, SS Group Leader and Lt. Gen. of the Waffen-SS Breithaupt, SA Group Leader Bunge, SA Group Leader and State Secretary Köglmaier, and, representing the Reich Attorney General, First State's Attorney Bischoff,
find:
That Alexander Schmorell, Kurt Huber, and Wilhelm Graf in time of war have promulgated leaflets calling for sabotage of the war effort and for the overthrow of the National Socialist way of life of our people; have propagated defeatist ideas, and have most vulgarly defamed the Führer, thereby giving aid to the enemy of the Reich and weakening the armed security of the nation.
On this account they are to be punished by Death.
Their honour and rights as citizens are forfeited for all time.
Eugen Grimminger gave money to a person guilty of high treason in aid of the enemy. To be sure, he was not aware that by so doing he was aiding the enemy of the Reich. However, he was aware that this person might use the money for the purpose of robbing our people of their National Socialist way of life. Because he gave support to high treason, he is sentenced to jail for a ten-year term, together with loss of honourable estate for ten years.
Heinrich Bollinger and Helmut Bauer had knowledge of treasonable conspiracy but failed to report it. In addition, the two listened to foreign radio newscasts dealing with the war and with events inside Germany. For this they are sentenced to jail for a term of seven years and loss of citizen's honour for seven years.
Hans Hirzel and Franz Müller - both immature boys misled by enemies of the state - gave support to the spread of treasonous propaganda against National Socialism. For this action they are sentenced to five years' imprisonment.
Heinrich Guter had knowledge of propagandistic intentions of this sort but failed to report them. For this he is sentenced to eighteen months' imprisonment.
Gisela Schertling, Katharina Schüddekopf, and Traute Lafrenz committed the same crimes. As girls, they are sentenced to one year's imprisonment.
Susanne Hirzel assisted in the distribution of treasonous leaflets. To be sure, she was not aware of their treasonous nature, but she was guilty in that in her inexcusable credulousness and good faith she did not seek certainty concerning the matter. She is sentenced to six months' imprisonment.
In the case of all the accused who have been sentenced to jail or imprisonment, the People's Court will accept as part of the punishment the time already spent in police and investigative custody.
Falk Harnack likewise failed to report his knowledge of treasonous activity. But such unique and special circumstances surround his case that we find ourselves unable to punish his deed of omission. He is accordingly set free.
