Answer with Explanation:
1. It becomes clear that Mr. Birling is unaware of the grumblings on the ground, for in fact, the "labour trouble" worsened in the past. This means that having another strike from the miners will have no more effect on Mr. Birling because he stated that he has seen the worst of the scenario. This means that he hasn't been able to address the miner's complaint and it's happening again, thus it becomes a dramatic irony.
2. Germans declared war against the USA in December 1941. It is clear that Mr. Birling is one-sided on this. The war happened under the leadership of Adolf Hitler. Almost everyone knows this and Mr. Birling claiming that the German didn't want war, is clear demonstration of dramatic irony. He also said that only the "half-civilized folks in the Balkans" wanted war. This shows how arrogant he is against half-civilized folks and their connection to having war. So, according to him, if you're a half-civilized person, you'll surely want to have war.
