Irony is ever present in Remarque's novel

Irony is ever present in Remarque's novel, from the lies told by hypocrites pushing young men to war to the very title of the novel itself. How is irony explored in the novel? Scenes of particular interest could be Paul's time in the trench with the dead French soldier, Paul's return home, Kat's death, and the novel's final moments. Another angle might be to consider this novel as a kind of Bildungsroman, chronicling the spiritual maturity of its hero, Paul, that nevertheless ends the way that it ends, tragically but also ironically.
