Re: Odd or amusing things to wonder while watching Thor...
I find it odd that the Asgardians have a weapon with which they could destroy Jotunheim with ease.
Of course, under Odin's rule, they never would do such a thing. They don't commit genocide.
But let's look at it from a frost giant point of view: Laufey tells Odin that they are at war now. Would you declare war on someone who has a superior weapon that can destroy you without any effort?
Would Iran declare war on the US and think "Of course the Americans have atomic weapons... but we are sure they won't use them"?
Laufey's war on Asgard is pointless. He cannot win. If the Asgardians felt that they were losing the war, they could always say "Stop it, Laufey, or we'll consider using the Bifrost against your world."
