1LT Watada is not nearly as smart as he thinks he is:

His lawyer, Eric Seitz, said he has lined up two witnesses to support the soldier's claim that the war violated domestic and international law: University of Illinois professor Francis Boyle, an international law expert, and Denis Halliday, a former United Nations assistant secretary-general.

The good LT is getting court martialed, and his defense is that two people with no legal standing will prove that the war is immoral? This isn't the Scopes monkey trial, which I suppose is what Watada believes this will be. That he'll sit by smugly while superior witnesses prove beyond a shadow of a doubt the illegality of this war, and then the military judge will be forced to find him guilty for missing movement but will sentence him to nothing, and a whole gallery of tie-dye wearing grandmas will raise up in Christian hymn (though not, I assume, Onward Christian Soldiers) while they carry him out of the building high upon their shoulders.

Meanwhile, everyone else watching this sees the LT ground-guiding the backhoe up to the hole to try and dig it just a little deeper. He's in way over his head, with a cheering section of idiots to prod him right off the cliff. The LT believes he'll be a hero, the hippies want a good martyr, and he's going to seriously regret this series of decisions when he reaches a military detention facility to find that those sharing his quarters don't really agree with his idea of speaking truth to power.
